This is an overview of the most frequently occurring problems encountered when assembling the printed circuit board (pcb) projects. It is important to carefully read the General Instructions included with the projects that point out essential information related to soldering and each electrical component. One simple rule that can save time is to double check that the component is in the correct position on the board before soldering. If the circuit is not functioning, the following should be examined.

• Inspect all solder joints. Adjacent components may be bridged together or the joint may need additional solder for good electrical continuity.

• Resistors installed in the wrong position on the board. Each resistor has a

specific value and therefore must be installed in the correct location. Resistors out of place can limit the circuit from functioning correctly to not functioning at all.

• Components with polarity (+/-) are installed incorrectly. It is critical to install

the correct lead in the correct hole to establish electrical continuity.

• IC-Chip installation or orientation incorrect on board. Refer to the General Instructions.

Those are the necessary tips when we do the trouble shooting. When we check some difficult project we also check about the BGA components with the X-Ray. So that to discover about the problem like insufficient soldering issue ,and if customer give test methord we will test the functional performance.
