Manufacturing copper clad laminate involves precise processes to ensure consistent quality and performance. Here take the double-sided copper clad laminate as a case. The production of double-sided copper clad laminates generally follows these steps:<\/p>\n\n\n\n<p><strong>1. Film Printing<\/strong> \u2013 Prepare and print the design film.<\/p>\n\n\n\n<p><strong>2. Board Cutting<\/strong> \u2013 Cut the board to size, keeping a 20mm process edge.<\/p>\n\n\n\n<p><strong>3. Drilling<\/strong> \u2013 Set the board thickness to 2.0mm or 1.6mm, ensuring the drill tip is 1-1.5mm above the PCB surface. Use <em>Create-DCM<\/em> software to generate U00 format drill files for CNC machines.<\/p>\n\n\n\n<p><strong>4. Polishing<\/strong> \u2013 Remove surface oxidation, oil stains, and burrs from drilling.<\/p>\n\n\n\n<p><strong>5.<\/strong> <strong>Hole Inspection<\/strong> \u2013 Ensure hole clarity for proper chemical penetration. Inspect the drilled and polished board under light to check if the holes are clear and unobstructed.<\/p>\n\n\n\n<p><strong>6. Pre-soaking<\/strong> \u2013 Remove oil, oxidation, and copper powder while adjusting the charge for better carbon particle adsorption.<\/p>\n\n\n\n<p><strong>7. Water Rinsing<\/strong> \u2013 Thoroughly rinse with clean water to remove chemical residues.<\/p>\n\n\n\n<p><strong>8. Drying<\/strong> \u2013 Eliminate residual moisture inside the holes using a drying oven or electric blower.<\/p>\n\n\n\n<p><strong>9. Activation<\/strong> \u2013 Coat the inner hole walls with nano-carbon particles to enhance conductivity.<\/p>\n\n\n\n<p><strong>10.<\/strong> <strong>Through-Hole Processing<\/strong> \u2013 Remove excess activation liquid to ensure all holes remain open using a vacuum cleaner.<\/p>\n\n\n\n<p><strong>11.<\/strong> <strong>Curing<\/strong> \u2013 Secure carbon particles to the hole walls and dry them with airflow.<\/p>\n\n\n\n<p><strong>12.

Copper Plating<\/strong> \u2013 Immerse in a copper plating bath for 20-30 minutes at a current of approximately 3-4A\/d\u33a1 (adjust as needed). This process ensures electrical conductivity by plating copper on the hole walls.<\/p>\n\n\n\n<p><strong>16. Water Rinsing<\/strong> \u2013 Clean the surface after plating.<\/p>\n\n\n\n<p><strong>17.<\/strong> <strong>Drying<\/strong> \u2013 Dry the board and remove any residual moisture in the holes.<\/p>\n\n\n\n<p><strong>18.<\/strong> <strong>Lamination<\/strong> \u2013 Apply the dry film using a lamination machine.<\/p>\n\n\n\n<p><strong>19. Exposure<\/strong> \u2013 Expose the film to light for approximately 3 minutes. &nbsp;Align the film (<em>negative film at this stage<\/em>) with the board first.&nbsp;Ensure correct alignment of the negative film for double-sided circuits.<\/p>\n\n\n\n<p><strong>20.<\/strong> <strong>Developing<\/strong> \u2013 Remove unexposed film in a developing solution at 45-50\u00b0C while observing changes on the board.<\/p>\n\n\n\n<p><strong>21. Water Rinsing<\/strong> \u2013 Rinse thoroughly to remove residues.<\/p>\n\n\n\n<p><strong>22. Etching<\/strong> \u2013 Etch at 45-50\u00b0C to remove unwanted copper.<\/p>\n\n\n\n<p><strong>23. Water Rinsing<\/strong> \u2013 Wash off any remaining etchant to prevent further corrosion.<\/p>\n\n\n\n<p><strong>24.
