5. Drilling - the process of drilling all of the holes for plated through applications; a drilling that is second is useful for holes which are not become plated through. Info on hole location and dimensions are contained in the drill file that is drawing.

6. Plating - the process of applying copper plating towards the pads, traces, and drilled through holes which are become plated through; panels are positioned in an electrically charged bath of copper.

7. Second Drilling - that is required when holes can be drilled via a copper area however the gap just isn't become plated through. Prevent this process if possible because it adds price to the finished board.

8. Masking - the process of using a protective masking product, a solder mask, on the bare copper traces or higher the copper which has had a thin layer of solder used; the solder mask protects against environmental damage, provides insulation, protects against solder shorts, and protects traces that run between pads.

I could tell you that around 40 per cent of total defective monitors are easy to be fixed usually while the remainder is a bit time intensive but it is well worth to perform electronic component analyzing, assessment and replacement. Once you got to blame, you solder it away and replace the brand new part and solder it straight back regarding the circuit board.

One of the most crucial and crucial approaches to servicing lcd monitor is the SOLDERING strategy that may bring you fast dollars easily and quickly. I think many repairers will agree with me personally.

Let just take few soldering that is real as follows:

Case 1: Compaq FP731 shutdown from couple of seconds to minutes that are few

Solution 1: Re-solder the feedback circuit of this ccfl inverter section C215, C216, D201, D204, R215, R246, R218, D206, C242, D210, R234, R243

Situation 2: BenQ T705 got display shutdown after power on for few second

Solution 2: Solder out 4 nos. shorted C5707 transistors and solder transistors that are new.
