How to prevent PCB warpage Warping circuit boards can cause misalignment of the components. When the circuit board is bent at SMT or THT, the components and pins are not full, which will bring a lot of difficulties to the assembly and installation work. IPC-6012, SMB – SMT boards have a maximum warp or twist…
How to output gerber 274x format file from eagle ? 1. Why should output Gerber 274X format file for PCB manufacturing? Gerber X2 file there are stack up information, but some CAM software are not support it, means it is can not input to CAM software. 2. It is easy to do output gerber 274x…
Whether it is in the manufacturing assembly process or in actual use, it is essential that the PCB has reliable performance. In addition to the associated costs, defects in the assembly process may be carried into the final product by the PCB, and failure may occur during actual use, resulting in a claim. Therefore, from…
