We are making this Burn-in Circuit Board by applying electrical excitation to the sample. The PCB aging process at the time of production is usually carried out at 125oC. We promote the aging process by using aged plates loaded with samples. These aged sheets were then inserted into an aging furnace which supplied a voltage to the sample while maintaining the furnace temperature at 125 °C. The applied electrical bias of this Burn-in Circuit Board can be static or dynamic. As a leading PCB manufacturer, MOKO offers the most reliable aged printed circuit boards on the market today. Its options include special plates, SMT components and multi-layer slabs with traces only on the inner layer. Its standard plated through holes provide high temperature plastics and contacts. Compressed mounting sockets are also available in high temperature materials. Burn-in Circuit Board is designed with trace width and length in mind, as well as characteristic impedance and signal termination.
