layers: 18SolderMask Color: Green Thickness: 5.4±0.5mmBorehole thickness -diameter ratio: 5.3133Surface treatment: ENIGApplication: transformer This printed circuit board is used for transformer, the surface treament is ENIG. A board used for transformer, needs to go through high temperatures. The usage of ENIG is to achieve good electrical performance in the long term use of PCB. The general process is pickling cleaning → micro-etching → pre leaching → activation → electroless nickel plating → chemical leaching.
Surface treatment: Leard free HAL Board thickness: 1.6mm, the thickness of 1.6mm is normal for PCB board thickness. Inner copper: 2OZ, the normal specification for the Copper Thicknes is 1OZ. The thicker copper (that is, 2OZ is thicker than 1OZ), the greater the current that can be carried.Min.line width / space: 0.1/0.1mm Min hole: 0.3mmApplication: automotive This project is for our customer from Czech Republic, their headquarters is in Germany. Every time they purchase PCBs from us, we ship the PCBs on time. Delivering the PCB on time can make sure the production schedule.So customer estacblishs a log time coopearetion with our company. Any feedback from customer is treated as our chance to continuously improve ourself.
Surface treatment: Leard free HAL Board thickness: 1.6mm, the thickness of 1.6mm is the PCB board thickness usually used for. Inner copper: 2OZ, the board Copper Thicknes usually made by 1OZ. The thicker copper that board has, the greater current can carry. Min.line width / space: 0.1/0.1mm Min hole : 0.3mm Application: automotive PCB used for automotive electronics usually requiring high-precision multilayer. The quality has passed the certificate of international quality system. With the high standard for quality, our company is aspired to be top PCB enterprise.Our company has much experience in technology innovation, risk control, and industrial standards.
