Pre-wave soldering preparation

1. In the PCB to be welded (the PCB has been coated with adhesive tape, SMC/SMD patches, cementing and completion of the THC plug-in process) after attaching to the components of the welding surface coating resistance or paste resistance, in order to prevent wave soldering after the solder plug, such as a larger size slot and hole application of high temperature adhesive tape affixed to prevent wave soldering time welding Tin flow to the upper surface of the PCB.

2. Measure the proportion of flux with the proportion, if the ratio is significant, dilute with thinner.

3. Pour flux into wave soldering flux trough.
