Without a functional PCB, an arcade cabinet is non-operational, as all game logic, visuals, and audio depend on it.<\/p>\n\n\n\n<p>Arcade PCBs come in different form factors, single-board (classic games) and multi-board (complex modern arcades), and vary by era, with older 8-bit\/16-bit models having simpler components than modern ones with multi-core processors. Regardless of type, their core purpose is to turn electronic signals into an interactive arcade gaming experience.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_Identify_Arcade_PCB\"><\/span>How to Identify Arcade PCB?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><strong>Identifying an <a href=\"https:\/\/www.bestpcbs.com\/blog\/2026\/04\/arcade-pcb\/\" title=\"\">arcade PCB<\/a> is straightforward once you know what to look for start with the most visible features, then move to component details.<\/strong> The first step is to check for labels or silk-screened text on the board itself; most manufacturers print the game title, model number, or manufacturer name directly on the PCB (usually near the edge or center). If no label exists, focus on the components and form factor.<\/p>\n\n\n\n<p>Use this table to compare key identifying features of common arcade PCB types, making it easy to distinguish between models:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>PCB Type<\/strong><\/td><td><strong>Key Identifying Features<\/strong><\/td><td><strong>Common Examples<\/strong><\/td><\/tr><tr><td>Single-Board Classic<\/td><td>Small to medium size (6-12 inches), 8-16 ROM chips, silk-screened game title, edge connector for power\/controls<\/td><td>Pac-Man, Space Invaders, Donkey Kong<\/td><\/tr><tr><td>Multi-Board System<\/td><td>Multiple connected PCBs (CPU, graphics, sound), larger size, more components, separate power connectors for each board<\/td><td>Street Fighter II, Mortal Kombat, Tekken<\/td><\/tr><tr><td>Modern Arcade PCB<\/td><td>Slim design, fewer physical components (integrated chips), USB or HDMI connectors, compatibility with modern displays<\/td><td>Newer fighting games, racing arcades, retro console ports<\/td><\/tr><tr><td>Bootleg PCB<\/td><td>No brand labeling, mismatched components, poor soldering, generic silk-screen text<\/td><td>Unlicensed copies of classic games<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p><strong>Additional tips:<\/strong> Count the IC chips (integrated circuits) with 8 or more pins this can help narrow down the game type. Check for a notch or arrow on the PCB, which indicates the orientation of components like ROM chips. If you\u2019re still unsure, take clear photos of the board (both sides) and compare the component layout to known arcade PCB databases or repair guides.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_Much_Voltage_Does_Arcade_PCB_Need\"><\/span>How Much Voltage Does Arcade PCB Need?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><strong>Most<a href=\"https:\/\/www.bestpcbs.com\/blog\/2026\/04\/arcade-pcb\/\" title=\"\"> arcade PCBs<\/a> require three primary DC voltages to operate, with +5V being the most critical.<\/strong> The exact voltage requirements vary slightly by PCB model, but the standard ranges are consistent across most arcade machines. You must match the voltage supply to the PCB\u2019s specifications too much voltage will fry components, while too little will cause the game to malfunction or not start at all.<\/p>\n\n\n\n<p><strong>Here\u2019s the breakdown of standard arcade PCB voltage requirements, organized by importance:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>+5V DC:<\/strong> This is the primary voltage for the PCB\u2019s core components (CPU, RAM, ROM chips, logic circuits). 90% of arcade PCBs use +5V as their main power source, with a tolerance of \u00b10.2V (so 4.8V to 5.2V is acceptable). A stable +5V supply is non-negotiable fluctuations will cause game crashes, glitches, or permanent component damage.<\/li>\n\n\n\n<li><strong>+12V DC:<\/strong> Used for audio amplifiers, coin door lights, LED strips, and some auxiliary components. Most PCBs draw minimal current from +12V, but it\u2019s still required for full functionality (especially sound). The tolerance here is \u00b10.5V (11.5V to 12.5V).<\/li>\n\n\n\n<li><strong>-5V DC:<\/strong> Less common in modern arcade PCBs, but essential for sound circuits in older games (1980s and early 1990s). If your PCB has a dedicated sound chip (e.g., YM2612), it may require -5V with a tolerance of \u00b10.2V (-5.2V to -4.8V). Newer PCBs often omit -5V, as their sound circuits are powered by +5V or +12V.<\/li>\n<\/ul>\n\n\n\n<p><strong>Amperage is just as important as voltage.<\/strong> Most arcade PCBs require a power supply that can deliver 2-5 amps (A) at +5V, 1-2A at +12V, and 0.5A or less at -5V (if needed). Always check the PCB\u2019s silk-screen or the game manual for exact amperage requirements using a power supply with insufficient amperage will cause voltage drops and system failures.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_Check_Arcade_PCB_Voltage\"><\/span>How to Check Arcade PCB Voltage?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><strong>Checking arcade PCB voltage is a simple process that requires a digital multimeter no advanced tools needed.<\/strong> The goal is to verify that the PCB is receiving stable, correct voltage from the power supply, which helps diagnose issues like game crashes, no power, or glitches. Follow these steps exactly to avoid damaging the PCB or multimeter:<\/p>\n\n\n\n<p><strong>1. Prepare the tools: <\/strong>Get a digital multimeter, and set it to DC voltage mode (look for the \u201cV\u2393\u201d symbol). Set the range to 20V (this covers all standard arcade voltages, so you won\u2019t need to adjust it). Ensure the multimeter\u2019s batteries are working test it by touching the two probes together; it should read 0V.<\/p>\n\n\n\n<p><strong>2. Power off the arcade machine:<\/strong> Unplug the power cord from the wall outlet to avoid electric shock. Wait 30 seconds to allow capacitors to discharge this prevents residual voltage from interfering with the test.<\/p>\n\n\n\n<p><strong>3. Locate the power connector on the PCB:<\/strong> The power connector is usually a small plastic block with pins labeled \u201c+5V,\u201d \u201c+12V,\u201d \u201c-5V,\u201d and \u201cGND\u201d (ground). If the labels are missing, refer to the PCB\u2019s silk-screen or game manual to identify the pins.<\/p>\n\n\n\n<p><strong>4. Power on the machine: <\/strong>Plug the power cord back in and turn on the arcade machine. Do not touch any components on the PCB while it\u2019s powered on static electricity or accidental contact can damage sensitive chips.<\/p>\n\n\n\n<p><strong>5. Test the voltage: <\/strong>Hold the multimeter\u2019s black probe (negative) firmly against the GND pin. Use the red probe (positive) to touch the +5V pin first. The multimeter should read between 4.8V and 5.2V. Repeat for the +12V pin (11.5V to 12.5V) and -5V pin (-4.8V to -5.2V, if present).<\/p>\n\n\n\n<p><strong>6. Interpret the results:<\/strong> If the voltage is within the acceptable range, the power supply is working correctly. If it\u2019s too high or too low, the power supply is faulty and needs to be replaced. If the voltage fluctuates (e.g., jumps from 4.5V to 5.5V), the power supply is unstable and should be replaced immediately to prevent PCB damage.<\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\"><\/ol>\n\n\n\n<p><strong>Pro tip:<\/strong> Test the voltage at both the power supply connector and the PCB\u2019s power pins. If the voltage is correct at the power supply but incorrect at the PCB, there\u2019s a loose wire or damaged connector that needs to be fixed.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.bestpcbs.com\/blog\/wp-content\/uploads\/2026\/04\/Arcade-PCB-2-1.jpg\"><img decoding=\"async\" src=\"https:\/\/www.bestpcbs.com\/blog\/wp-content\/uploads\/2026\/04\/Arcade-PCB-2-1.jpg\" alt=\"Arcade PCB, https:\/\/www.bestpcbs.com\/blog\/2026\/04\/arcade-pcb\/\" class=\"wp-image-23809\"\/><\/a><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_Hook_Up_Arcade_PCB\"><\/span>How to Hook Up Arcade PCB?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><strong>Hooking up an arcade PCB is a step-by-step process that requires connecting power, controls (joysticks, buttons), display, and sound.<\/strong> The key is to match the PCB\u2019s connectors to the corresponding components in the arcade cabinet misconnections will cause malfunctions or damage. Follow these steps for a safe, successful setup:<\/p>\n\n\n\n<p>1. <strong>Prepare the cabinet:<\/strong> Ensure the arcade cabinet is powered off and unplugged. Remove the back panel to access the interior. Clear any dust or debris from the cabinet to avoid short circuits.<\/p>\n\n\n\n<p>2. <strong>Mount the PCB:<\/strong> Use screws to secure the PCB to the cabinet\u2019s mounting bracket. Ensure the PCB is level and not touching any metal components (this prevents short circuits). Use standoffs if needed to elevate the PCB slightly.<\/p>\n\n\n\n<p>3. <strong>Connect the power supply:<\/strong> Plug the power supply\u2019s connector into the PCB\u2019s power port. Match the pins carefully most power connectors are keyed (have a notch) to prevent reverse insertion, but double-check the labels (+5V, +12V, -5V, GND) to be sure. Do not force the connector if it doesn\u2019t fit, it\u2019s oriented incorrectly.<\/p>\n\n\n\n<p>4. <strong>Connect controls:<\/strong> The PCB has a dedicated connector for joysticks and buttons (often called a \u201ccontrol harness\u201d). Plug the control harness into the PCB\u2019s control port. Each button and joystick direction is wired to a specific pin refer to the PCB\u2019s manual to ensure the harness is connected correctly. Test the controls by pressing buttons and moving the joystick; if they don\u2019t respond, check the wiring.<\/p>\n\n\n\n<p>5. <strong>Connect the display:<\/strong> Most arcade PCBs use a VGA, HDMI, or RGB connector for the display. Plug the display cable into the PCB\u2019s display port and the other end into the arcade\u2019s monitor. Ensure the display is set to the correct resolution (most classic PCBs use 4:3 aspect ratio).<\/p>\n\n\n\n<p>6. <strong>Connect sound:<\/strong> Plug the speaker wires into the PCB\u2019s audio port (labeled \u201cAUDIO OUT\u201d or \u201cSPEAKER\u201d). If the PCB has separate left and right audio channels, connect each wire to the corresponding speaker.<\/p>\n\n\n\n<p>7. <strong>Test the setup:<\/strong> Plug in the power cord and turn on the arcade machine. The game should boot up, and all controls, display, and sound should work. If there\u2019s no power, check the power supply and connections. If the game boots but controls don\u2019t work, recheck the control harness.<\/p>\n\n\n\n<ol start=\"7\" class=\"wp-block-list\"><\/ol>\n\n\n\n<p><strong>Pro tip:<\/strong> Take photos of the original PCB\u2019s connections before removing it (if replacing an old PCB). This makes it easy to match the wiring to the new PCB.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_Connect_Speakers_to_Arcade_PCB\"><\/span><strong>How to Connect Speakers to Arcade PCB?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><strong>Connecting speakers to an arcade PCB is simple, but you must match the speaker\u2019s impedance (ohms) to the PCB\u2019s audio output to avoid damaging the sound chip.<\/strong> Most arcade PCBs work with 8-ohm or 4-ohm speakers check the PCB\u2019s silk-screen or manual for the exact impedance requirement. Follow these steps to connect speakers correctly:<\/p>\n\n\n\n<p>1. <strong>Gather the tools:<\/strong> You\u2019ll need speakers (matching the PCB\u2019s impedance), speaker wire (18-22 gauge), wire strippers, and electrical tape (or heat shrink tubing).<\/p>\n\n\n\n<p>2. <strong>Prepare the speaker wire:<\/strong> Cut two lengths of speaker wire (long enough to reach from the PCB to the speakers). Strip 1\/4 inch of insulation from each end of the wire to expose the copper strands. Twist the strands together to prevent fraying.<\/p>\n\n\n\n<p>3. <strong>Locate the PCB\u2019s audio port:<\/strong> The audio port is usually labeled \u201cAUDIO OUT,\u201d \u201cSPEAKER,\u201d \u201cLEFT,\u201d or \u201cRIGHT.\u201d Most PCBs have two terminals (positive and negative) for each speaker look for \u201c+\u201d and \u201c-\u201d labels.<\/p>\n\n\n\n<p>4. <strong>Connect the wire to the PCB:<\/strong> Attach one end of the speaker wire to the PCB\u2019s positive terminal (+) and the other end to the negative terminal (-). Use electrical tape to secure the wires to the terminals this prevents them from coming loose.<\/p>\n\n\n\n<p>5. <strong>Connect the wire to the speaker:<\/strong> Attach the other end of the wire to the speaker\u2019s positive and negative terminals (match \u201c+\u201d to \u201c+\u201d and \u201c-\u201d to \u201c-\u201d). Again, secure the wires with electrical tape or heat shrink tubing.<\/p>\n\n\n\n<p>6. <strong>Test the sound:<\/strong> Turn on the arcade machine and play a game. The sound should be clear and free of distortion. If there\u2019s no sound, check the wire connections (ensure they\u2019re secure and matched correctly) or test the speakers with another device to confirm they\u2019re working.<\/p>\n\n\n\n<ol start=\"14\" class=\"wp-block-list\"><\/ol>\n\n\n\n<p><strong>Note:<\/strong> If the PCB has a built-in audio amplifier, you can connect speakers directly. If not, you\u2019ll need an external amplifier between the PCB and speakers connect the PCB\u2019s audio output to the amplifier, then the amplifier to the speakers.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_Test_Arcade_PCB\"><\/span><strong>How to Test Arcade PCB?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><strong>Testing an arcade PCB ensures it\u2019s functional before installing it in a cabinet, saving you time and frustration.<\/strong> The test covers power, graphics, sound, and controls, and requires a few basic tools: a power supply (matching the PCB\u2019s voltage), a display (monitor or TV), speakers, and a control harness (joystick and buttons). Follow these steps to test the PCB thoroughly:<\/p>\n\n\n\n<p>1. <strong>Set up the test bench:<\/strong> Place the PCB on a non-conductive surface (e.g., a wooden table) to prevent short circuits. Connect the power supply to the PCB\u2019s power port ensure the voltage and amperage match the PCB\u2019s requirements.<\/p>\n\n\n\n<p>2. <strong>Connect the display:<\/strong> Plug the display cable into the PCB\u2019s display port and turn on the display. Set the display to the correct input (e.g., VGA, HDMI).<\/p>\n\n\n\n<p>3. <strong>Connect speakers:<\/strong> Attach speakers to the PCB\u2019s audio port (as outlined in the previous section).<\/p>\n\n\n\n<p>4. <strong>Connect controls:<\/strong> Plug the control harness (joystick and buttons) into the PCB\u2019s control port.<\/p>\n\n\n\n<p>5. <strong>Power on the PCB:<\/strong> Turn on the power supply. The PCB should power up within 2-3 seconds, and the display should show the game\u2019s title screen or boot sequence.<\/p>\n\n\n\n<p>6. <strong>Test graphics:<\/strong> Check for clear, distortion-free visuals. Look for glitches, missing sprites, or color issues these indicate a faulty graphics chip or ROM.<\/p>\n\n\n\n<p>7. <strong>Test sound:<\/strong> Play the game and listen for clear audio. Check for static, distortion, or missing sound effects this could mean a faulty sound chip or speaker connection.<\/p>\n\n\n\n<p>8. <strong>Test controls:<\/strong> Press all buttons and move the joystick in all directions. Ensure each input is registered in the game (e.g., the character moves when the joystick is pushed, buttons trigger actions).<\/p>\n\n\n\n<p>9. <strong>Test stability:<\/strong> Let the game run for 10-15 minutes. If it crashes, freezes, or resets, there\u2019s a problem with the power supply, overheating, or a faulty component (e.g., a bad ROM chip).<\/p>\n\n\n\n<ol start=\"20\" class=\"wp-block-list\"><\/ol>\n\n\n\n<p><strong>If the PCB fails any test:<\/strong> Check the power supply voltage (as outlined earlier), inspect for loose components or damaged traces, and test the ROM chips (see the next section). For more complex issues, use a multimeter to check for continuity in the PCB\u2019s traces.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_Use_an_Arcade_PCB\"><\/span><strong>How to Use an Arcade PCB?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><strong>Using an arcade PCB is simple once it\u2019s properly hooked up, but there are a few key steps to ensure optimal performance and longevity.<\/strong> Whether you\u2019re using a classic or modern PCB, follow these guidelines to get the most out of your arcade machine:<\/p>\n\n\n\n<p>1. <strong>Power on correctly:<\/strong> Always turn on the arcade machine\u2019s power supply first, then the display. This prevents voltage spikes from damaging the PCB\u2019s components. When turning off, reverse the order: turn off the display first, then the power supply.<\/p>\n\n\n\n<p>2. <strong>Monitor temperature:<\/strong> Arcade PCBs generate heat during operation, especially older models. Ensure the cabinet has proper ventilation (e.g., fans, vents) to prevent overheating. Avoid placing the cabinet in direct sunlight or near heat sources (e.g., radiators).<\/p>\n\n\n\n<p>3. <strong>Handle with care:<\/strong> Never touch the PCB\u2019s components while it\u2019s powered on. If you need to adjust connections or inspect the board, turn off the power and unplug the machine first. Use an anti-static wristband to prevent static discharge, which can destroy sensitive chips.<\/p>\n\n\n\n<p>4. <strong>Load games correctly:<\/strong> For PCBs with removable ROM chips, ensure the chips are seated properly (see the next section) before powering on. If the game doesn\u2019t load, check the ROM chips for damage or misalignment.<\/p>\n\n\n\n<p>5. <strong>Perform regular checks:<\/strong> Every 1-2 months, power off the machine, unplug it, and inspect the PCB for dust, loose components, or corrosion. Clean the PCB (as outlined below) to prevent dust buildup, which can cause short circuits.<\/p>\n\n\n\n<p>6. <strong>Troubleshoot minor issues:<\/strong> If the game glitches or freezes, power off the machine, wait 30 seconds, then power it back on. This often resolves temporary issues caused by voltage fluctuations or overheating. If the problem persists, check the power supply and connections.<\/p>\n\n\n\n<ol start=\"29\" class=\"wp-block-list\"><\/ol>\n\n\n\n<p><strong>Pro tip:<\/strong> For vintage PCBs, avoid leaving the machine on for extended periods (e.g., 8+ hours) to reduce wear on components. Modern PCBs are more durable but still benefit from occasional breaks to prevent overheating.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><a href=\"https:\/\/www.bestpcbs.com\/blog\/wp-content\/uploads\/2026\/04\/Arcade-PCB-.jpg\"><img decoding=\"async\" src=\"https:\/\/www.bestpcbs.com\/blog\/wp-content\/uploads\/2026\/04\/Arcade-PCB-.jpg\" alt=\"Arcade PCB, https:\/\/www.bestpcbs.com\/blog\/2026\/04\/arcade-pcb\/\" class=\"wp-image-23806\" style=\"aspect-ratio:3\/2;object-fit:contain;width:800px\"\/><\/a><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_Clean_Arcade_PCB\"><\/span><strong>How to Clean Arcade PCB?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><strong>Cleaning an arcade PCB is critical for preventing malfunctions dust, dirt, and corrosion can cause short circuits, poor connections, and component failure.<\/strong> The process is simple but requires care to avoid damaging sensitive components. Use only the right tools and cleaning solutions to ensure safety and effectiveness:<\/p>\n\n\n\n<p>1. <strong>Prepare the tools:<\/strong> You\u2019ll need high-purity isopropyl alcohol (IPA, 90% or higher) or anhydrous ethanol (99% or higher), anti-static wristband, soft-bristled brush (e.g., an old toothbrush), lint-free cloths (or coffee filters), and a small container for the cleaning solution. Avoid low-purity alcohol as it contains too much water and can cause corrosion.<\/p>\n\n\n\n<p>2. <strong>Power off and disconnect:<\/strong> Unplug the arcade machine and remove the PCB from the cabinet. Put on the anti-static wristband to prevent static discharge. Place the PCB on a non-conductive surface.<\/p>\n\n\n\n<p>3. <strong>Remove loose dust:<\/strong> Use the soft-bristled brush to gently sweep away loose dust and debris from the PCB\u2019s surface and components. Be careful not to bend any pins or damage small components (e.g., capacitors).<\/p>\n\n\n\n<p>4. <strong>Clean with alcohol:<\/strong> Pour a small amount of IPA or ethanol into the container. Dip the lint-free cloth or a cotton swab into the solution (don\u2019t soak it just dampen it). Gently wipe the PCB\u2019s surface, focusing on areas with visible dirt, grease, or corrosion. For hard-to-reach areas (e.g., between components), use a cotton swab.<\/p>\n\n\n\n<p>5. <strong>Clean connectors and pins:<\/strong> Use a cotton swab dampened with alcohol to clean the PCB\u2019s edge connector and component pins. This removes oxidation and dirt that can cause poor connections.<\/p>\n\n\n\n<p>6. <strong>Dry the PCB:<\/strong> Allow the PCB to air dry in a well-ventilated area for at least 30 minutes (or overnight for best results). Do not use a hair dryer or heat source this can damage components. Ensure the PCB is completely dry before reconnecting it to the power supply.<\/p>\n\n\n\n<p>7. <strong>Reassemble:<\/strong> Once dry, reattach the PCB to the cabinet and reconnect all cables. Power on the machine to confirm it\u2019s working correctly.<\/p>\n\n\n\n<ol start=\"35\" class=\"wp-block-list\"><\/ol>\n\n\n\n<p><strong>Note:<\/strong> Avoid using water, harsh chemicals, or abrasive materials (e.g., paper towels) as these can damage the PCB\u2019s solder mask and components. For heavy corrosion, use a specialized electronic cleaner (ensure it\u2019s compatible with PCBs) and a small brush to gently remove the corrosion.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_Remove_ROM_Chips_from_Arcade_PCB\"><\/span><strong>How to Remove ROM Chips from Arcade PCB?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><strong>ROM chips (Read-Only Memory) store the game\u2019s software, and removing them may be necessary for repairs, upgrades, or replacement.<\/strong> The process requires care to avoid damaging the ROM chip or the PCB\u2019s socket. Follow these steps to safely remove ROM chips:<\/p>\n\n\n\n<p>1. <strong>Prepare the tools:<\/strong> You\u2019ll need an EPROM puller (preferred) or a small flathead screwdriver, anti-static wristband, and a clean, dry surface to place the ROM chips.<\/p>\n\n\n\n<p>2. <strong>Power off and disconnect:<\/strong> Unplug the arcade machine and remove the PCB from the cabinet. Put on the anti-static wristband to prevent static discharge.<\/p>\n\n\n\n<p>3. <strong>Locate the ROM chips:<\/strong> ROM chips are rectangular integrated circuits (ICs) with 16-40 pins, usually seated in a socket on the PCB. They are often labeled with the game\u2019s title or a part number.<\/p>\n\n\n\n<p>4. <strong>Identify the notch:<\/strong> Each ROM chip has a small notch on one end, which indicates pin 1. The PCB\u2019s socket will also have a notch or arrow to match the chip\u2019s orientation note this before removing the chip to ensure correct reinstallation.<\/p>\n\n\n\n<p>5. <strong>Remove the chip:<\/strong> If using an EPROM puller, clamp the puller around the edges of the ROM chip (avoid touching the pins) and gently pull straight up. If using a screwdriver, insert the flathead between the chip and the socket (on one side) and gently twist to lift the chip slightly. Move the screwdriver to the other side and repeat until the chip is loose, then pull it straight up. Do not pry too hard this can damage the socket or the chip\u2019s pins.<\/p>\n\n\n\n<p>6. <strong>Store the chip:<\/strong> Place the removed ROM chip on an anti-static mat or in an anti-static bag. Label the chip with the game title and its position on the PCB (e.g., \u201cROM 1\u201d) to avoid confusion if you\u2019re reinstalling it later.<\/p>\n\n\n\n<ol start=\"42\" class=\"wp-block-list\"><\/ol>\n\n\n\n<p><strong>Pro tips:<\/strong> Remove one ROM chip at a time to avoid mixing them up. If the chip is stuck, gently rock it back and forth (without bending the pins) to loosen it. Never remove or insert ROM chips while the PCB is powered on this will fry the chip and possibly the PCB.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><a href=\"https:\/\/www.bestpcbs.com\/blog\/wp-content\/uploads\/2026\/04\/Arcade-PCB-1.jpg\"><img decoding=\"async\" src=\"https:\/\/www.bestpcbs.com\/blog\/wp-content\/uploads\/2026\/04\/Arcade-PCB-1.jpg\" alt=\"Arcade PCB, https:\/\/www.bestpcbs.com\/blog\/2026\/04\/arcade-pcb\/\" class=\"wp-image-23807\" style=\"aspect-ratio:3\/2;object-fit:contain;width:800px\"\/><\/a><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"FAQs_About_Arcade_PCB_Board\"><\/span>FAQs About Arcade PCB Board<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><strong>Q1: Why won\u2019t my arcade PCB power on even with the correct voltage?<\/strong><\/p>\n\n\n\n<p><strong>A1: Common issues: loose power connections, faulty power supply, damaged power connector.<\/strong> Check connections, test power supply with a multimeter, clean or replace damaged connector; replace faulty voltage regulator if needed.<\/p>\n\n\n\n<p><strong>Q2: How do I know if my arcade PCB\u2019s ROM chips are bad?<\/strong><\/p>\n\n\n\n<p><strong>A2: Signs: game crashes, missing graphics, distorted sound, blank screen. <\/strong>Check ROM seating first; test with an EPROM programmer if issues persist.
