The entire process of manufacturing printed circuit boards follows the actions below for some applications:
Fundamental Steps for Production Printed Circuit Boards:
1. Setup - the process of determining materials, processes, and requirements to meet the customer's requirements for the board design based on the Gerber file information supplied with the purchase purchase.
2. Imaging - the entire process of moving the Gerber file - http://kscripts.com/?s=Gerber%20file information for a layer onto an etch resist film that is placed in the copper layer that is conductive.
3. Etching - the standard procedure of exposing the copper as well as other areas unprotected by the etch resist movie to a chemical that eliminates the unprotected copper, leaving the protected copper pads and traces in spot; more recent processes use plasma/laser etching instead of chemical compounds to get rid of the copper product, allowing finer line definitions.
4. Multilayer Pressing - the entire process of aligning the conductive copper and insulating dielectric layers and pressing them under heat to trigger the adhesive within the dielectric layers to form a solid board product.

Did this make sure they are plumbers that are bad?
Not by way of a shot.They that is long good at there work.
As being a mater of reality, they showed me how to install pex tubing with out placing a kink into the tubing.
In return We revealed them how to solder copper pipeline.
The end result, one of them used knowledge I taught 'em, while another forgot a few important actions and caused a major drip.
