Rigid PCB Has A Certain Degree Of Toughness

Jun 05, 2017

The common thickness of rigid PCBs is 0.2mm, 0.4mm, 0.6mm, 0.8mm, 1.0mm, 1.2mm, 1.6mm, 2.0mm, etc.

Rigid PCB materials include: phenolic paper laminates, epoxy paper laminates, polyester glass felt laminates, epoxy glass cloth laminates

Material selection of the main considerations of the value of the value of the material as the focus of the commonly used alternative 1, the general Tg: S1141; S6018 (RCC) 2, the Tg: IT158; S1000; are "lead-free" compatible materials; S1170: the current mainstream use of the Tg 170-180 material; S1000-2: high Td Tg 170-180 material; S1170 further upgrade; IT180: performance Similar to S1000-2; FR-406: ISOLA products; Rigid PCB performance and S1141 170 close

In the future, large printed circuit board suppliers will focus on soft printed circuit boards and substrates, Rigid PCB while maintaining rigid PCB status.

Rigid PCBs On the most basic printed circuit boards, the parts are concentrated on one side and the wires are concentrated on the other side. Because the wires only appear on one side, Rigid PCB the printed circuit board is called a single panel. Because the single-panel has many stringent restrictions on the design line (because only one side, the wiring can not cross and must be around the path), so the early circuit to use such circuit boards.

Both sides of the circuit board are wired. In order to connect the wires on both sides, Rigid PCB it is necessary to have an appropriate circuit connection between the two sides. The connection between these circuits is called the guide hole. The guide hole is on the printed circuit board, filled with or coated with metal holes, it can be connected with the two sides of the wire. Because the area of the double panel is doubled over the single panel and the wiring can be staggered (can be routed to the other side), the double panel can be used on more complex circuits than the single panel.

Rigid PCB board is made of paper-based (commonly used in single-sided) or glass cloth (commonly used in double-sided and multi-layer), pre-phenolic or epoxy resin, one or both sides of the surface layer The This PCB copper clad sheet, we call it a rigid plate. And then made into PCB, we call it rigid PCB rigid board is not easy to bend, with a certain toughness of the rigid substrate made of printed circuit board, Rigid PCB the advantage is that it can be attached to the electronic components to provide some support The
