Latest Trends in PCB Manufacturing

1. Environmental Protection in PCB Manufacturing

• Reduction of Lead Content:
  The shift towards whole board plating and lead-free solder materials is accelerating to meet environmental regulations.
• Reduction in Formaldehyde Usage:
  Environmental concerns are driving the industry to find alternatives to formaldehyde in the electroplating process.
• Advancements in MID Technology:
  Thermoplastic resins and recyclable materials are being utilized in Molded Interconnect Devices (MID) to replace traditional PCBs.
• Exploring Other Eco-Friendly Materials:
  Development of solder resist materials and non-halogen substrates is on the rise to align with environmental standards.

2. High-Speed Circuits

High-speed circuits operating above 45MHz are becoming more prevalent, with a focus on managing signal transmission effects for optimal performance.

3. V-CUT Method

The V-CUT technique involves cutting a circuit board to form a V-shaped groove, allowing for manual breaking or the use of a jig for separation.

4. Gold Finger

Gold Finger, found on circuit board edges like network cards, refers to gold-plated connectors shaped like fingers for enhanced connectivity.
