FPC proofing price and FPC panel need attention
We need to know the price of FPC proofing. First of all, we need to know what FPC FPC is. FPC is a kind of flexible circuit board with high reliability and flexibility, which is made of polyimide or polyester film. It has the characteristics of high wiring density, light weight, thin thickness and good bending. After we know what FPC FPC is, we can talk about the price of FPC proofing.
FPC proofing quotation panel specification:
1. The outer frame (clamping edge) of the circuit board panel shall adopt the closed-loop design to ensure that the FPC panel will not deform after being fixed on the fixture.
2. There shall be no large devices or protruding devices near the connection point between the panel outer frame and the internal small panel, and there shall be more than 0.5mm space between the components and the edge of the FPC panel to ensure the normal operation of the cutting tool.
3. Four positioning holes shall be made at the four corners of the panel outer frame, with the hole diameter of 4mm ± 0.01mm; the strength of the hole shall be moderate to ensure that it will not break during the process of upper and lower plate; the hole diameter and position accuracy shall be high, and the hole wall shall be smooth without burr.
4. Each small board in the circuit board assembly shall have at least three positioning holes, 3 ≤ hole diameter ≤ 6 mm, and no wiring or patch is allowed within 1 mm of the edge positioning hole.
Price calculation method for FPC FPC proofing:
1. Calculate the price according to the size. The manufacturer will give the unit price per square meter according to different FPC flexible circuit board layers and different processes. Customers only need to change the size of FPC flexible circuit board into meters and then multiply the unit price per square meter to get the unit price of the circuit board to be produced. This calculation method is very suitable for FPC flexible circuit board of ordinary processes.
2. The price is calculated according to the cost refinement, because the raw material of FPC FPC FPC is copper clad plate, and the factory that produces the copper clad plate has determined some fixed sizes to be sold on the market. The manufacturer will calculate the utilization ratio of FPC FPC FPC FPC according to the material, layer, process, quantity and other parameters of the circuit board to be produced, so as to calculate the material cost.
