We need to know the price of flexible FPC proofing. We must first know what is FPC flexible circuit board. FPC is a flexible circuit board with high reliability and flexibility, which is made of polyimide or polyester film as the base material. It has the characteristics of high wiring density, light weight, thin thickness and good bendability. After understanding what these FPC flexible circuit boards are, we can talk about the price of flexible FPC proofing.
FPC proofing quotes specification issues:
1. The outer frame (clamping edge) of the circuit board jigsaw should adopt a closed loop design to ensure that the FPC jigsaw will not be deformed after being fixed on the fixture.
2. There must be no large devices or protruding devices near the connection points between the outer frame of the puzzle and the inner small board, and between the small board and the small board, and there must be more than 0.5mm of space between the edges of the components and the FPC board. To ensure that the cutting tool runs normally.
3. Four positioning holes are opened at the four corners of the outer frame of the jigsaw, with a hole diameter of 4mm ± 0.01mm; the strength of the hole must be moderate to ensure that it will not break during the upper and lower plates; the hole and position accuracy should be high, and the hole wall should be smooth without burrs .
4. Each small board in the circuit board puzzle must have at least three positioning holes, 3 ≤ aperture ≤ 6 mm, and no wiring or patch is allowed within 1 mm of edge positioning holes.
FPC flexible circuit board proofing price calculation method:
1. Calculate the price according to the size. The manufacturer will give the unit price per square meter according to the number of FPC flexible circuit board layers and different processes. The customer only needs to change the size of the FPC flexible circuit board to meters and then multiply it by the unit price per square meter. The unit price of the circuit board to be produced can be obtained. This calculation method is very suitable for the FPC flexible circuit board of ordinary technology.
2. Calculate the price according to the cost, because the raw material of the FPC flexible circuit board is copper clad laminates. The factories that produce the copper clad laminates have fixed sizes and sold them on the market. Manufacturers will use the materials, number of layers, Process, quantity and other parameters are used to calculate the utilization rate of copper clad laminates for this batch of FPC flexible circuit boards, so as to calculate the material cost.
