The entire process of manufacturing printed circuit boards follows the steps below for many applications:

Basic Steps for Manufacturing Printed Circuit Boards:

1. Setup - the process of determining materials, procedures, and demands to meet the consumer's specifications for the board design on the basis of the Gerber file information supplied with the purchase order.

2. Imaging - the entire process of transferring the Gerber file information for the layer onto an etch resist film that is positioned on the conductive copper layer.

3. Etching - the traditional process of exposing the copper and other areas unprotected by the etch resist film to a chemical that eliminates the copper that is unprotected leaving the protected copper pads and traces in place; newer processes use plasma/laser etching instead of chemicals to remove the copper product, allowing finer line definitions.

4. Multilayer Pressing - the process of aligning the conductive copper and insulating dielectric layers and pressing them under temperature to stimulate the adhesive into the dielectric levels to create a solid board product.

Additionally it is a useful practice to fill a gap between two metal components for the strong joint. Here is a synopsis regarding the various techniques:

Welding

The welding method is best as soon as the two metals joined are similar. For instance, it isn't possible to weld steel to a little bit of copper. Welding relies on a really high temperature to melt the components. This form of joining procedure is extremely reliable while the joint is just as strong as the two initial pieces that were jointed together. In certain situations you'll be able to work with a filler metal to enhance in the strength that is all-round. But, it is essential to perform this work using the proper number of heat. Making use of heat that is too much lead to a weak weld and a change in the steel's properties. You will find multiple welding practices, including stir friction, laser, electron beam, arc and steel inert gas. The welding procedure normally widely used to cut through large steel structures by just utilizing heat to melt through.
