Q.P.I.’s service doesn’t stop after a product has been delivered. Q.P.I. believes in the importance of aftercare and support. Q.P.I.’s After Sales department is responsible for this service. This department can help you with questions about the product and can also carry out analyses. Q.P.I. always uses the 8D reporting method for these analyses. Using this system the whole production chain can be analysed and if necessary changes can be made to the production process.
Printed Circuit Board Processing
When it comes to processing printed circuit boards it’s important to choose the right type of finish and to make good preparations for the actual assembly.
It’s important during preparation to dry the printed circuit boards. A lot of substrate materials are naturally hygroscopic, which means that the material absorbs moisture. Due to the rapid heating during the soldering process this moisture cannot escape from the substrate quickly enough. The vapour that arises then causes a very large internal pressure in the printed circuit board. These forces are so great that they can cause physical damage to the printed circuit board. Q.P.I. has set-up a drying specification that can be downloaded here.
