The PCB prototype is a provider of electrical connections for electronic components, and is widely used. Below we share some PCB board maintenance common sense.

1, look at the status of components. The first observation circuit board has no obvious damage of components, such as electrolytic capacitor and resistor, burn out and burned to power device loss etc..

2, look at the circuit board welding. Such as printed circuit boards have deformed; there is no soldering off, obvious weld; circuit board copper skin have cocked, burnt black.

3, Observe the plug-in of component. Such as integrated circuits, diodes, circuit boards, power transformers and other directions are not inserted wrong.

The correct judgment of the fault can be solved effectively. We also provide rogers PCB, fast PCB prototype etc. Welcome to choose us.
