(5) Reduce customer costs, save customer time, and ensure 100% success rate

PCB copying is to clone and prototype the circuit board when there is a PCB circuit board, replace the components, make a BOM list, make a PCB file, and export a schematic diagram. We can also provide customers with PCB modification boards (addition and decrease functions, board size changes, board material changes, combining several boards into one board). PCB change board.

If you want to be able to do the reverse, you can also do the forward, that is, PCB LAYOUT. As long as customers provide schematic diagrams, or only provide circuit board samples, or only provide product function descriptions to us, we can provide customers with positive hardware circuit designs and provide customers with qualified PCB board drawings.

Professional PCB company is engaged in PCB design, PCB copy board, PCB conversion board, complete solution of electronic products, one to 28-layer high-density PCB copy board, single-sided board, multi-layer board, multi-level laser blind buried via production capacity, Mass processing of high-precision PCB boards with a line width of 3mil (0.075mm) and an aperture of 4mil (0.10mm).

As long as one motherboard, the one-time copy is successful, and we promise to be 100% exactly the same as the original. The cost of copying the board is low, which saves the design cost for customers. Save R&D time several times! Save high salary of R&D staff!

FPC basic knowledge explanation

[FPC: Flexible Printed Circuit (Flexible Printed Circuit) is a highly reliable and excellent flexible printed circuit board made of polyimide or polyester film. It has the characteristics of high wiring density, light weight, thin thickness and good bendability.

The basic structure of FPC

Copper foil substrate: FCCL copper foil substrate is divided into electrolytic (ED) copper and rolled copper (RA). The thickness is conventionally 1/3 1oz (mainstream manufacturers Taihong, Lianmao, Doosan, Xinyang) 1/2oz and 1/3 oz (Electrolytic copper is cheaper to manufacture but more fragile, and rolled copper is expensive to manufacture but softer)

Cover film: Coverly

Reinforcement board: generally divided into PI or FR4 material

EMI: Electromagnetic shielding film (mainstream manufacturers: Topaz, Toyo, Chengbang Dali, Fangtie)

1. PCB single-sided board manufacturing process

Cutting - Pasting Dry Film - Alignment - Exposure - Development - Graphic Plating - Stripping - Surface Treatment - Covering Film - Pressing - Curing - Immersion of Nickel and Gold - Printing Characters - Cutting - Electrical Test - Punching - Final Inspection - Packaging - Shipment

Detailed PCB process:

Cutting material: cut the copper foil of the future material to the appropriate size

Drilling: Use a drill to drill holes in the copper foil according to the Layout drawing

Black hole: physical action of graphite and carbon powder to form a conductive film on the hole wall, and then directly form copper on the hole wall by electroplating

Immersion nickel gold: FPC leakage copper surface increase or decrease gold plating is to enhance FPC conductivity, welding performance, oxidation resistance, but in order to prevent the gold layer from penetrating into the copper layer, leading to gold infiltration, it is necessary to plate a layer of nickel on the copper surface. For isolation, nickel is too thick and has high hardness, poor flexibility, too thin and poor strength, and it is easy to fall off.
