Etched PCBPosted by PCB Assembly on December 21st, 2018 PCB etching process is one of the major steps in the chemical processing of subtractive printed circuit board. It is the removal of copper, to achieve the desired circuit patterns. In PCB etching process, all copper is removed except the circuitry that is protected by the tin plating applied during the previous treatment in PCB manufacture. The tin is then stripped and the copper is cleaned and the newly prepared circuit is ready for solder mask. ALLPCB is capable of small volume SMT prototyping PCBs with both automated and manual assembly. Our advanced PCBA quality inspection equipment ensures that your finished project is of the highest quality. ALLPCB has AOI inspection with IPC610-D standards for every components avoids the soldering defects and SMT automatic inspection ensures that every resistance is within standard range. It has authoritative guarantee of quality. Like it? Share it! |
