Can the PCB not be cleaned?

When troubleshooting a non-functional or poor performance circuit, engineers can usually run simulations or other analysis tools to consider the circuit from a schematic level. If these methods don't solve the problem, even the best engineers may be stumped, frustrated or confused. Thermal Management manufacturer china

Some materials used in PCB assembly or modification can cause serious circuit functionality problems if the PCB is not properly cleaned. One of the most common problems with this type of phenomenon is flux.

The properly cleaned and dried boards performed well and did not drift at any point in the test. Back Plane manufacturer china

In summary, improper solder cleaning can cause severe performance degradation, especially in high-precision DC circuits. For all manually assembled or modified PCBs, be sure to use an ultrasonic bath (or similar) for final cleaning. After air drying with an air compressor, the assembled and cleaned PCB is baked at a slightly elevated temperature to remove any residual moisture. We usually bake at 70 ° C for 10 minutes.

This simple “keep clean” technique should help you dramatically reduce the time spent troubleshooting and help you spend more time designing high-precision circuits!
