FAQs About PCB Manufacturing

• Does Copper Foil Thickness Affect LED Service Life?

  The thickness of copper foil impacts thermal conductivity of the aluminum substrate, influencing LED service life.

• Why Are Small Holes Drilled in PCBs?

  Small holes, or vias, connect electrical signals between PCB layers.

• What Temperature is Ideal for Soldering?

  Generally, soldering iron temperature ranges from 200 to 300 degrees for different solder joint sizes.

• Importance of Filming Aluminum Substrates

  Unfilmed substrates are prone to scratches and oxidation, impacting manufacturing processes.

• Soldering LED Beads on Aluminum Substrates

  Hand soldering LED beads on aluminum substrates is commonly done using a heating table for precise removal.

• Decoding Circuit Board Labels

  Understanding labels like R+, R-, L+, L- helps identify channel polarity and signal directions.

• Types of Circuit Boards

  From high precision to flexible printed boards, various types like gold-plated and rigid-flex serve different purposes.

• Main Board PCB Selection

  For main switch boards, cost-effective four-layer PCBs are common, with six-layer boards offering enhanced functionality.

• Laminating Process for Multilayer PCBs

  The lamination process bonds conductive layers and insulating materials to create stable multilayer PCBs with prepreg.
