Yet, the word “bridging” inside thePCBAfield refers to a completely other process when used in tandem with soldering. One form of problem that might happen while soldering is called solder bridging. It is a problem that could have an effect on production, call for reworks. This could possi...
Peelable solder mask, also known as temporary solder mask, is a type of solder mask coating that can be partially peeled off to expose selected areas of the PCB copper for soldering components, thereby eliminating the need to undergo a complex masking andetchingprocess to create openings in the...
Different masking materials exist such as lead-free solder, immersion silver, lead solder, etc. The last step necessary for the process of fabrication is screen printing the circuit board, therefore making the legend and labels to appear at the right locations.

easier to weld. 3. In the PCB proofing process, both nickel-gold electroplating and immersion gold are surface treatment processes. The difference is that nickel-gold electroplating is done before solder masking; while immersion gold is done after soldering masking. Hope the above knowledge can pro...
To the first limit switch solder a pair of 40cm wires to the normally open pins - for me this the centre pin and the pin where the arm connects. This is the brown and pink wires in the second photo above. The next two switches are connected in series with a 40cm wire (grey in ...

A clean metal surface is more readily wetted by molten solder or braze.Foundries and Forges – In foundries and forges, abrasive blasters like centrifugal wheel blasters and pressure blasting equipment are vital for cleaning operations. After shakeout, castings are blasted with metal shot or grit ...
David is President at R&D Technical Services, a vapor phase reflow oven manufacturer. he has 20 plus years experience in the vapor phase reflow industry. I would need to see samples to be sure, but I would bet that the solder balls are forming because the solder in the joints is being ...
lamination process that stacks layers of substrate material and copper foil, which is then bonded together using heat and pressure. This process is then followed by the typical process of PCB fabrication, that is: drilling, electroplating, etching, and solder-masking to create the desired circuit ...
