PCB substrate:
The base material is generally classified according to the insulation, material composition or flame resistance of the substrate. The common raw materials are bakelite, glass fiber, and various plastic boards. Manufacturers of PCB substrates generally use an insulating prepreg composed of glass fiber non-woven fabrics and epoxy resin resins, and then press them with copper foil to form a copper foil substrate for use.
The following are the more common types of PCB substrates:
FR-4: Glass fiber + epoxy resin. It is the most commonly used PCB material, but the Tg is only about 130. If the subsequent processing environment of the product or the operating environment temperature is high, High Tg FR-4 is recommended.
High Tg FR-4: Glass fiber + epoxy resin, the use is second only to FR-4. Tg above 150°C is High Tg.
CEM-1: The center is tissue paper, and the surface is covered with glass cloth + epoxy resin.
CEM-3: The center is glass non-woven cloth, and the surface is covered with glass cloth + epoxy resin.
Ceramic substrate (Ceramic PCB): ceramic powder + glass fiber.
Teflon PCB (Teflon PCB): Teflon + glass fiber.
Panel, as the name implies, is to assemble one or several single-board PCB prototype service into the same Panel.
The purpose of the panel:
The original veneer is too small, and it is not easy to pick up after the PCB prototype service is formed or after the PCBA.
After the panels are assembled, the cost of the test fixture and the test man-hours can be saved, and the efficiency can be improved.
The single board is too small or there is no optical point (Fiducial mark) in the single board, but the PCB prototype service has SMT requirements.
There is no hole in the veneer board to fix the PIN for CNC molding, so it is necessary to add a break-away, drill a PIN hole and place an optical point (Fiducial mark).
For the efficiency of SMT printing. At the current speed of the placement machine, the PCB prototype service passes through the placement machine once, and the number of seconds spent on each board will not be too different. Therefore, the utilization of the appropriate single board to form a Panel is relatively high.
Increase the board edge (Break-away) for track conveying during PCBA production.
