TIME FOR THE ETCHING & SOLDERING PROCESS

METHODOLOGY

CONTENT:



PCB etching is as simple as immersing it in the etchant solution and agitating it to keep sludge from inhibiting further etching. This can be done in plastic or glass trays, vertical etching tanks, or spray etchers. The goal of all of these methods is to dissolve all of the exposed copper and leave all of the unexposed copper. The acid FERRIC III CLORIDA is use in this process in order to ensure that all the connection can allow the current flow through the copper connection. The difference is throughput. A hobbiest is most likely to use a tray or a vertical tank.

Soldering is a process in which two or more metal items are joined together by melting and flowing a solder into the joint, the filler metal having a lower melting point than the workpiece. Soldering differs from welding in that soldering does not involve melting the work pieces.. Formerly nearly all solders contained lead, but environmental concerns have increasingly dictated use of lead-free alloys for electronics and plumbing purposes. Soldering is the only permanent way to ‘fix’ components to a circuit. However, soldering requires a lot of practice as it is easy to ‘destroy’ many hours preparation and design work by poor soldering. If we follow the right guideline, we can have a good connection on the PCB board.



OBJECTIVES:

  • To move to the next step before reach to the final part of the completing this project.
  • To learn how the correct way in order to etching and solder all the component in the PCB board.
  • To allow the current flow through the connection and make the component function well.
CONCLUSION:

I already done finish the important part that can allow me to see the whole of operation in this project. I can learn a lot of things in order to make it connect correctly.
