5. Drilling - the process of drilling all the holes for plated through applications; a 2nd drilling process is used for holes that are not to be plated through. Information on opening location and dimensions are within the drill drawing file.

7. 2nd Drilling - that is required whenever holes can be drilled via a copper area however the gap isn't become plated through. Prevent this process if at all possible since it adds price to the board that is finished.

8. Masking - the process of applying a protective masking material, a solder mask, over the bare copper traces or over the copper that has had a thin layer of solder used; the solder mask protects against ecological harm, provides insulation, protects against solder shorts, and protects traces that run between pads.

Case 3: Dell e151fp ( comparable to Acer Chassis that is FP553 energy or power on then shutdown briefly

Solution 3: Solder out the faulty C605, C707, C703 capacitor, the defective power UC3842B that is ic resistors R613, R623, R615, faulty transistor Q601, defective diode D604= 1N4148 and fuse F601. Solder the new parts straight back into the circuit.

No matter how severe fault level of lcd monitor, the soldering work is always involved in repairing lcd monitor from above examples. You will find the next articles explain the soldering that is basic advance soldering means of the surface mounted devices (SMD) on our site.
