LED Lighting: MC-PCBs

Wednesday, November 13th, 2019

LEDs are pretty hot nowadays! Not just the biggest tendency in lighting, but also require a lot of heat dissipation that standard PCB material just can’t handle. So what’s the solution? Metal PCBs. Standard PCB material typically has a thermal conductivity of 0.5 W/m K; which is not adequate for the current high intensity LEDs. With MCPCB materials you can increase the life of your LEDs with better heat dissipation.

What’s the thermal conductivity of MCPCB material?

Up to now, Best Technology has helped many customers with their MCPCB needs and have found the most common questions as shown below:

What is the most cost effective MCPCB?

How do you layout an MCPCB?

Can I get a different dielectric thickness between the metal and circuit layer?

Can I put plated through holes on an MCPCB?

Can I do more than one layer with an MCPCB?

How quick can a MCPCB be manufactured?

What Metals can be used?

The professional staff at Best Technology can help you resolve these questions and even more. Need help getting started? Contact us today.

PCB Assembly Fabrication Methods

Tuesday, November 12th, 2019

PCB or Printed Circuit Board assembly at Best Technology involves combining the bare PCB, electronic components, and other accessories effectively to allow the assembly to function as the designer intended. Generally speaking, the fabrication methods involve a number of major steps:

(1)Component placement

(2)Soldering

(3)Cleaning

(4)Inspection

(5)Testing

Component Placement

Methods of placing components on the PCB rely on several factors such as:

Single or double side component placement

SMD components only

Through-hole (TH) components only

Mix of SMD and through-hole components

A PCB may have components present only on one of its sides or on both, although assembling a PCB with through-hole components on both sides is a rare occurrence. Single side component placement with either all SMDs or all through-hole components is more common, while single sided PCBs with a mix of SMDs and through-hole components is also to be found.

For assemblies requiring SMDs on both sides of the PCB or a mix of SMD and through-hole components on the top and only SMDs on the bottom, the PCB assembly process must be broken up into several intermediate steps, and the assembler needs to take special precautions for each of them.

Soldering

Soldering is the process of joining two dissimilar metals using a molten filler metal alloy. The molten metal alloy enters the joint, and as it cools and solidifies, bonds with the adjoining metals. Primarily,  three common ways of soldering including manual soldering, wave soldering and reflow soldering are available.

Cleaning

After soldering is over, some flux residue may remain on the printed circuit board. Over time, this can turn acidic, and corrosively damage solder joints. The flux residue can also attract fingerprints and make the PCB look unclean.

Manual Inspection

Inspection is necessary at various stages of assembly. For instance, one stage of inspection is necessary when the operator has stuffed TH components into the board, and again once the assembly has undergone wave soldering.

Similarly, for reflow soldering, inspection is necessary once after solder paste printing is over, then again after mounting the SMD components, and once again after the boards have exited the reflow oven.

AOI & X-Ray Inspection

For large batches of PCB assembly, the manual inspection process may be too slow. A faster process is the Automatic Optical Inspection or AOI process. AOI machines have video cameras to capture images of the PCB, the components, and the solder quality, and they can compare the images with standard images in the machine’s memory. The AOI machines work at high speed processing a large number of PCBs within a relatively short time.

Electrical & Functional Testing

Electrical testing may be necessary after the assembly has passed through the above stages, to test whether the assembly functions as intended by the designer. This may involve programming the board, or calibrating certain components before the actual testing can begin.

Electrical and functional testing involves applying specific voltage/voltages to the circuit on the PCB and looking for normal/abnormal behavior at predefined outputs. Some tests may require a voltmeter and ammeter, while others may need more sophisticated instruments such as an oscilloscope or a waveform analyzer to complete the testing.

Conclusion

PCB assembly is a complicated process involving several technical processes with important setup parameters. Eminent assemblers such as Best Technology are always careful with these setup parameters to allow the final product achieve the desired quality.

The Basics of Printed Circuit Board Assembly(SMT)

Friday, November 1st, 2019

Printed circuit board assembly(SMT), also known as “stuffing” or “populating” the bare printed circuit board, is quite an intricate process which involves many different stages.  Best Technology’ in house printed circuit board assembly service makes ordering your turnkey printed circuit boards a hassle-free experience as you can count on the industry’s largest support team to help you control every step of the process.

Here are some of the basic elements involved in the printed circuit board assembly process:

Solder Paste – Solder paste is a combination of flux, a chemical created to assist in the bonding and melting of the metal, and small fragments of metal (solder) so as to apply the electronic components to the printed circuit board. The paste is placed on the board in specific places along the board in exact amounts with the use of a Solder Stencil and a paste application machine, automatically.

Pick and Place Machine – This machine is essential in an automated printed circuit board assembly process.  The machine is programmed to automatically coordinate with complete accuracy the places to precisely mount each electronic component to be soldered to the printed circuit board. These machines are exact and quick.

Infrared Reflow – After the precise bonding element (solder paste) is applied to the PCB, the board will be directed to the reflow oven to join the electronic components to the board by melting the solder paste. This “oven” is comprised of many heaters whose main function is to heat the board to a precise temperature and control the level of cooldown as the solder hardens. This process is crucial to the creation of properly functioning electronics. The printed circuit board will run through a series of testing to ensure no issues or short-circuiting nor misalignments have occurred.
