Detection of dry soldering point on single Printed Circuit Board (PCB) is important stage in electronic product. There are number of holes of different size and at a large number of positions (up to thousand) must be soldered on the PCB. It is very important to examine this printed circuits boards before using in any electronic device as it may contain faulty solder point. Also there is possibility of presence of dry soldering points because of which that electronic may not work properly. The authors are designing the assembly of circuit which will detect the dry soldering points on the PCB automatically &also gives the location of that dry soldering points on the PCB.
