I. Overview :
Blind-buried orifice plates are mainly used for high-density, small-microplate production. The purpose is to save circuit space, so as to reduce PCB volume, such as mobile phone boards. PCB manufacturer from China, PCB prototype manufacturing, PCB batch manufacturing - Juding Circuit Technology
PCB layout is designed to avoid the use of a single large pad between two interconnected SMD components in the PCB designBecause the solder on the large pad will pull the two components in the middle, the correct way is to separate the pads of the two components and connect them with thinner wires between the two pads. If the wires are required to pass a large current. Several wires can be connected in parallel; PCB manufacturer from China, PCB prototype manufacturing, mass production - Juding Circuit Technology
Currently, the typical process for printed circuit board (PCB) processing uses "graphic plating". That is, firstly, a layer of lead-tin resist is pre-plated on the portion of the copper foil to be retained on the outer layer of the board, that is, the pattern portion of the circuit, and then the remaining copper foil is chemically etched away, which is called etching.
FPC is a flexible electronic circuit board. The flexible circuit board is made of polyimide or polyester film and is a highly reliable and excellent flexible printed circuit board. Referred to as soft board or FPC, it has the characteristics of high wiring density, light weight and thin thickness.
FPC is mainly used in mobile phones, notebook computers, PDAs, digital cameras, LCM and many other products. The following coatings are used to introduce the commonly used terms of FPC.
