Circuit board open circuit is a problem that every PCB manufacturer often encounters. It has been plagued by production and quality management personnel. It causes replenishment due to insufficient shipments, delivery delays, and customer complaints that are more difficult for the industry to solv

There are two common processes for printed circuit boards: tin spraying and tin sinking, both of which are surface treatment methods to meet the requirements of lead-free soldering. But in the circuit board process, tin sinking is not known to most people. The following editor will talk about the di

With the advancement of technology, some electronic products such as mobile phones and tablet computers have become light, small and portable. The electronic components used in SMT processing are also becoming smaller. The previous 0402 resistors and capacitors have also been used in large numbers.

High-level circuit boards are generally defined as 10 layers - 20 or more layers of high-layer circuit boards, which are more difficult to process than traditional multi-layer boards, and have high quality and reliability requirements, mainly used in communication equipment, high-end servers, medica
