If you have the opportunity to pick up a printed circuit board and observe it alittle, you willfind that there are many large and small holes on the circuit board. Take it up and look at the lamp on the ceiling, and you will find many densely packed small holes. The holes are not placed in a good place, each hole is designed with a purpose. Commonly drilled holes in our printed circuit board(PCB) ...

As the current design of portable products is developing toward miniaturization and high density,the difficulty of PCB design is also increasing, which puts forward higher requirements for PcB processing technology. Most of the current portable products use the BGA package with a pitch of less than 0.65mm, and the design process of blind and buried holes is used. So what is a blind and buried hole...

A Thick Copper PCB, also known as a Heavy Copper PCB, is a type of printed circuit board that features copper traces and planes with significantly higher copper thickness compared to standard PCBs. While standard PCBs typically have copper thickness measured in ounces (e.g., 1 oz, 2 oz), Thick Copper PCBs can have copper thicknesses ranging from 3 oz to as high as 20 oz or more. The increased copp...
