4) Basic soldering strategy

5) Advanced Smd soldering technique

6) Quick and soldering station that is inexpensive

As soon as you master the soldering skill, it is possible to use this skill that is useful fix the fault electronic component on any circuit panels. Begin training and practice make perfect.

In electronic devices, printed circuit boards, or PCBs, are used to mechanically support components that are electronic have their connection leads soldered onto copper pads in surface mount applications or through rilled holes in the board and copper pads for soldering the component leads in through-hole applications. A board design could have all through-hole components on top or side that is component a mix of through-hole and area mount on the top side only, a variety of through-hole and surface mount components on top part and area mount components on the bottom or circuit side, or area mount components on the top and bottom edges for the board.

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

6. Plating - the entire process of using copper plating towards the pads, traces, and drilled through holes that are to be plated through; panels are placed in an electrically charged bath of copper.

7. 2nd Drilling - that is required whenever holes can be drilled through a copper area however the opening isn't to be plated through. Prevent this process when possible as it adds price to the board that is finished.

8. Masking - the process of applying a protective masking product, a solder mask, within the bare copper traces or over the copper which has possessed a slim layer of solder used; the solder mask protects against environmental damage, provides insulation, protects against solder shorts, and protects traces that run between pads.
