Description |
Printed Circuit Board or Printed Wiring Board is the fundamental board formed with pattern filled with electric conductive parts on the surface of electroless circuit board in every
electronic products. Double sided boards have circuits formed on both sides of the boards. They can be categorized into two classes-one without through-hole metalization and one with through-hole metalization. There are two types of metallized through-holes lated-through holes(PTH) and silver-through holes(STH), in which the hole is completely filled with conductive silver ink. |
