The main advantages of PCB multi-layer boards: This circuit board is resistant to oxidation. Diverse structures, high density, and surface coating technology ensure the quality and safety of the circuit board and can be used safely.
"Via" refers to a common hole drilled at the intersection of the wires that need to be connected on each layer in double-sided and multi-layer boards to connect the printed wires between layers.
The phenomenon of PCB copper blistering is not uncommon in the electronics industry, and it poses potential risks to product quality and reliability.
Etching printed circuit boards is based on the interaction of chemicals with the metal surface, etching away the removed portion of the metal material to form the desired circuit pattern.
PCB circuit board in the production process there are a lot of bad problems occur, which tin beads caused by short-circuit failure and other problems, always let a person can not prevent.
Manufacturers of the most common three bell drilling design is divided into three main points “hole type” “hole properties” “hole between the moment”; let's learn together!
