| titleOfInvention | The test method of the matching of solder resist or marking ink and scaling powder |
| abstract | A kind of test method of the matching of solder resist or marking ink and scaling powder, successively include the following steps: (1) toward a temperature-controllable and temperature can be kept constant container in add heat transfer, and temperature is set within the scope of 200-300 DEG C；(2) etc. after the temperature of heat transfer is constant, printed circuit board is put into container and swims in printed circuit board on the surface of heat transfer, the surface that printed circuit board need to be tested is upward；(3) scaling powder is added dropwise on the surface that then need to be tested with Dropping feeder toward printed circuit board, starts simultaneously at timing；(4) when observing that solder resist or marking ink surface start blistering, removing, stop timing, and recording test time；(5) according to the length of testing time, the matching of solder resist or marking ink and scaling powder is evaluated.The present invention is simple and easy to do, can intuitively, effectively evaluate the superiority and inferiority of the matching of the scaling powder used when printed circuit board surface solder resist or marking ink and welding. |
