Tips for improving solder quality
As a professional and experienced PCB Manufacturer, China PCB Assembly has some suggestions for improving solder technology. The assembly of electronic components of this printed circuit board is very important. It affects all qualities and functions. So, the requirement for working condition and solder technology is quite strict. Manufacturers of PCBs need to make some process documents complicated and workable for solder electronics.
First of all, before the assembly of electronic components and soldering, the operator must be familiar with the corresponding requirements of drawings, component lists, and technical documents, etc. Then the operator can proceed with the assembly and solder components. For example, we will use an anti-static wristband and make sure that Grounding is done when soldering components with anti-static requirements.
Secondly, it is necessary to check PCBs and components before assembling electronic components and solder. If the PCB is not clean, you need to use degreasing cotton with a little ethanol to clean it. Regarding the components with pins, you need to check if they are in good lead solderability. If not, you need to add a tin to their pins. However, this method is not suitable for light diodes, swim, and …
