5. Drilling - the entire process of drilling most of the holes for plated through applications; a second drilling procedure is useful for holes which are not become plated through.
Information on hole location and dimensions are within the drill file that is drawing.

6. Plating - the entire process of applying copper plating towards the pads, traces, and drilled through holes which are to be plated through; boards are placed in a electrically charged bath of copper.

7. Second Drilling - this is required whenever holes are to be drilled through a copper area nevertheless the hole just isn't to be plated through. Prevent this process if possible as it adds cost to the board that is finished.

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

To understand about soldering irons for electronics and soldering irons cape town, please go to the page soldering iron.
I will inform you that approximately 40 % of total defective monitors are easy to be fixed generally while the sleep is really a bit time intensive but it is worth to execute component that is electronic, screening 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.


Perhaps one of the most important and essential techniques in servicing monitor that is lcd the SOLDERING method that will bring you fast dollars easily and quickly. I think most repairers will agree with me.

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 associated with inverter that is ccfl C215, C216, D201, D204, R215, R246, R218, D206, C242, D210, R234, R243

Case 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.
