how to find a fault in a circuit board

Regardless of whether you're not a specialist or a designer, some printed circuit board issues are self-evident. Regardless of whether for a PC, home theater framework or other techno-device, some normal and straightforward issues can cause a printed circuit board not to work. An intensive visual examination of any issue circuit board could spare you an excursion to the repair shop or an unnecessary investigation charge. Try not to be reluctant to observe. Simply ensure your energy is killed to ensure you don't get a jar.

Expel the cover from your gear. Most electronic and PC covers are hung on by four screws, two on each side close to the base. Expel the screws with the screwdriver and put them aside. Lift the cover off.

 Step 1

Verify whether all the circuit sheets (CB) are connected to firmly. You may have just a single, yet in the event that you have more, check them all. Numerous CB's have multi-stick edge connectors. Moving can make them work free. Push the cards delicately into their associating spaces to ensure they're connected the distance to.

Step 2 


Check singular module parts. A few chips, "little girl sheets" or "piggy back" sheets fit into their own particular attachments, and can have a free association. Haul them out and review them for filthy or consumed pins, and after that reseat by pushing them delicately set up so they are appropriately situated. The pins ought to be sparkly and brilliant on the off chance that they are perfect and not consumed.

Step 3


Search for water or remote protests anyplace on the circuit board. Now and again a paper cut dropped onto a circuit board can prevent it from working.

Step 4


Check auxiliary wiring plugs. Girl sheets and piggy-back sheets may have a link association that just pushes on. Some of these can work free in moving. Force them off, assess them for wear or erosion and after that supplant them to guarantee a cozy fit.

...

Search for remote items, water or consumed parts.

Search for darkened segments or softened or broken parts of the printed circuit follows, the little metal lines that associate segments together on the two sides of the board. Parts can wear out and when they do they can smoke. Additionally search for swollen or stained segments.

 step 5

Search for broken leads on the segments. A few segments have little wire drives that can without much of a stretch sever appropriate beside the circuit board or near the part itself. Gently shake bigger segments with wires to check whether a wire may be broken.

Step 6


Search for splits on the circuit board. A hairline split may not look excessively harming but rather it can incorporate broken circuit follows.
