Description

The entire process of manufacturing printed circuit panels follows the actions below for many applications:

Fundamental Steps for Manufacturing Printed Circuit Boards:

1. Setup - the entire process of determining materials, procedures, and requirements to meet the consumer's specifications for the board design in line with 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 placed regarding the copper layer that is conductive.

3. Etching - the standard procedure of exposing the copper and other areas unprotected by the etch resist film up to a chemical that removes the unprotected copper, leaving the protected copper pads and traces in place; more recent processes use plasma/laser etching instead of chemical substances 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 levels and pushing them under temperature to activate the adhesive into the dielectric levels to create a solid board product.

Given that the tops are tabbed, flip them all over (sunny side down), but, slip out of the tabbing strip through the first one so it lays throughout the straight back associated with next. Do the same most of the real way down your "string". You will be soldering - http://Browse.deviantart.com/?q=soldering the strip to your contact points on the relative back associated with cells. When your cells are like mine, you will see 6 tiny whitish contact squares. Ensure that your tab strips fall into line so they shall sit on the contact spots then use flux to the spots. Hold your soldering iron to your strip at that moment when its hot, touch the solder cable towards the point and let the solder movement, do not use too much and do not over temperature the contact because you can harm the cell. An alternative is to use a solder paste on the contact, lay the tab on and hold the iron on the point till it flows, for me, this is a better solution. Do the same for all six contact points, will have two cells linked. Continue this procedure for the cells that are solar the string.

It is a pretty good clear idea to check that you've got good solder connections, by exposing the cells to light and testing the production voltage. At least, check each string, it's far too late when you yourself have connected them all up to find you have a "dry solder" someplace and also have to trace it right back. With the string of cells all soldered together, there is yet another thing to do. During this period you should have at one end associated with the string, the last one, featuring its "top tabs" free. But at the start of the sequence, nothing to connect with. Which means you need to solder a brief amount of tabbing strip to the straight back of the "top" (first) cell to possess one thing in order to connect to and complete a circuit. Therefore, regarding the "first" cell, solder tabbing strips across the trunk contacts with enough of a free end to permit you one thing to connect to. Now you are going to have connecting tabs at both ends of the sequence willing to connect with its neighboring string or perhaps a connector bus. Actually, now it saves some double handling that you have read this far, its a good idea to do solder this "first" set of back tabs before soldering up a string.
