Mil-spec PCB Manufacturing

Comparing with common PCBs, mil-spec printed circuit boards have strict and different design requirements of DFM, testability, safety, EMC, LVD, EMI and so on, subsequently the process, manufacturing technologies, quality controls and cost performance will be involved for mil-spec PCB manufacturing. At the very beginning, we have to select suitable laminates, TG value and surface finish method to confront severe application conditions. The thermal design is very critical for mil-spec PCB manufacturing. We should consider positions of high heat dissipation components. In general, when component heat dissipation density is over 0.4W/cm3, we have to use condensers or junction bars.

Except the design phases and components selection, we also pay high attentions to the manufacturing process of mil-spec PCBs. In terms of precision and stability of mil-spec products, every single process should be under control such as copper thickness, laminate thickness, coating ink thickness, impedance, surface finish etc. All mil-spec PCB manufacturing will be in compliance with IPC standards (MIL-PRF-31032). Before shipment, all PCBs are tested according to product requirements. During stage of PCB assembly, all mil-spec PCBs should be under appropriate uniformity of solder paste, precise SMTs and temperature zones of reflow ovens. For quality inspection, these PCBs will be checked under AOI, flying probe and test frame. In this way, we can comply with our customer requirements of mil-spec PCB manufacturing.

 

With years experiences of military specification PCBs manufacturing, we are competent with your strict requirements. Your mil-spec products will be delivered fast and in high quality. Your project time-to-market is also treasured as ourselves. Hope to be your best PCB manufacturer.
