PCB e hollë
Prodhuesi dhe montimi i PCB-ve të hollë - Shërbim me një ndalesë
Sipas kërkesave dhe notave të ndryshme të PCB, materiali kryesor i substratit-petëzuar i veshur me bakër (PCB i hollë) ka shumë lloje të produkteve. Ato klasifikohen ndryshe sipas rregullave të ndryshme.
Sipas trashësisë së Laminatit të veshur me bakër, ai mund të ndahet në bord konvencional dhe bord të hollë. Rezina epoksi CCL që ka një trashësi (me përjashtim të trashësisë së fletës së bakrit) më pak se 0.8 mm zakonisht referohet si pllaka e hollë (standardi IPC është 0.5 mm). Laminat e veshura me bakër me bazë tekstil me fije qelqi epoxy me një trashësi 0,8 mm ose më pak mund të përdoren për shpime, dhe gjithashtu mund të përdoret si një fletë e brendshme thelbësore për prodhimin e bordit me shumë shtresa.
The conventional board thickness is 0.8mm – 1.6mm, while our FR4 single panel has the thinnest thickness of 0.2mm and the double-sided FR4 has the thinnest thickness of 0.3mm. Since the thickness is thin, the sheet has a certain degree of softness.
What is Flexible Circuit Board（thin PCB) ？
The flexible circuit board is actually a type of thin board. Flexible Printed Circuit (FPC) is a highly reliable and excellent flexible printed circuit board made of polyimide or polyester film. It has the characteristics of high wiring density, lightweight, thin thickness, and good bending property.
Flexible Printed Circuit (FPC), also known as flexible circuit board and flexible circuit board, is favored by its excellent characteristics such as lightweight, thin thickness, and free bending and folding. However, the quality inspection of FPC in China is good. It also relies mainly on manual visual inspection, which is costly and inefficient.
With the rapid development of the electronics industry, the design of circuit boards has become more and more high-precision and high-density. The traditional manual detection methods have been unable to meet the production requirements, and the automatic detection of FPC defects has become an inevitable trend of industrial development.
Flexible Printed Circuit (FPC) is a technology developed in the United States for the development of space rocket technology in the 1970s. It is made of polyester film or polyimide and has high reliability and excellent flexibility. The printed circuit, by embedding the circuit design on a flexible thin plastic sheet, allows a large number of precision components to be stacked in a narrow and limited space to form a flexion flexible circuit.
The circuit can be bent, folded, lightweight, small in size, good in heat dissipation, easy to install, and breaks through the traditional interconnection technology. In the structure of the flexible printed circuit, the constituent materials are an insulating film, a conductor, and an adhesive.
Flexible printed circuit (thin PCB) characteristics:
1. Short: short assembly time, all lines are configured. Eliminate the connection work of redundant cables
2. Small: smaller than the PCB, can effectively reduce the volume of the product, increase the convenience of carrying
3. Light: lighter than PCB (hardboard), can reduce the weight of the final product
4. Thin: The thickness is thinner than the PCB, which can improve the softness. Strengthen the assembly of the three-dimensional space in the limited space.
The Sheet is used in a wide range of applications. The main applications of the flexible printed circuit. Such as mobile phones, computers, and LCD screens, CD players, disk drives, hard disk drives (HDD) suspension circuits. Circuit) and xe package board and other components
