Heavy Copper PCB, pcb fabrication up to 12oz, large current, pcb fabrication base material is FR4/Teflon/Ceramic, pcb fabrication used in high-power power supply and motor circuits products. HUIHE CIRCUITS is one of the heavy copper PCB manufacturers , we have passed ISO9001/ISO13485/IATF16949/UL/RoHS/REACH certification.If you want to know more about thick copper pcb, heavy copper pcb, please contact HUIHE Circuits heavy copper pcb manufacturer . The Heavy Copper PCB plating process must achieve the following aspects: 1. HUIHE Circuits heavy copper pcb manufacturer adds a certain value according to the area value calculated by the computer and the empirical constant accumulated in the actual production to ensure the integrity of the plating layer in the hole. 2. When the heavy copper PCB is electroplated for 5 minutes, take out the substrate and observe whether the copper layer on the surface and the inner wall of the hole is intact. It is better that all the holes have a metallic ...

Through hole circuit board & half hole PCB , no copper burr residue or warpage in half hole, reduce connectors and save space, apply to Bluetooth module and Signal receiver products. HUIHE CIRCUITS PCB board with holes apply to Bluetooth module and Signal receiver products. Our PCB products have passed ISO9001/ISO13485/IATF16949/UL/RoHS/REACH certification. Production process of metallized half-hole PCB For the front inversion, to prevent the quality of the product and the need to make corrections in the later process, the production process of this type of board is processed according to the following process: a drilling (drilling, gong groove-plate surface plating-external Optical imaging-pattern plating-co-drying-half-hole processing-film stripping, etching, tin stripping-other processes-shape Main points of metallized half-hole PCB production The specific metallized PCB half hole are processed in the following way: all metallized half-hole PCB holes must be drilled in the ...

In order to shorten the signal transmission distance and reduce the signal transmission loss, the 5G communication PCB , gradually move towards high-density wiring, fine wire spacing, the development of small aperture, thin profile and high reliability. Process difficulty of high frequency and high speed communication circuit board Alignment accuracy Accuracy is tightened, and tolerance convergence between layers is required. The board size becomes more demanding for this convergence requirement Size gets bigger Machinability deteriorates, maneuverability deteriorates, and blind holes need to be buried 1. Cost increase 2. Difficulty in alignment accuracy Impedance accuracy The etching challenge is great: 1. The etching factor: the smaller the better, the etching accuracy tolerance is 10mil and the line width is controlled by +/-1MIL, and the line width tolerance above 10mil is controlled by +/-10%. 2. Higher requirements for line width, line spacing and line thickness. 3. Others: wir...
