PCB De-Paneling: V-cut scoring de-paneling and removing board edges
The term “V-cut” refers to a pre-cut separation groove made by printed circuit board (PCB) manufacturers at specific locations on the PCB. This groove is designed to facilitate the “de-paneling” process after the completion of surface mount technology (SMT) and … Continue reading

What is V-cut? Why PCB need to design V-cut on it?
The term “V-cut” in the context of printed circuit boards (PCBs) refers to predefined cutting lines made by PCB manufacturers based on customer drawings. These lines are typically arranged in a V-shaped pattern, resembling the letter “V,” which is why … Continue reading

Why is Panelization and Break-away Tab Necessary in PCB Manufacturing, then De-paneling after PCBA is Completed?
Why is “Panelization” performed during PCB manufacturing? And after surface mounting (SMT) assembly and wave soldering, why is it necessary to go through the additional process of “de-paneling” to separate the individual boards? What is the purpose of the PCB’s … Continue reading

An Option for Adding More Solder – Solder Preforms
“Solder preforms” are tiny pieces of solid tin alloy that are already shaped before use. They come in two types of flux contain and flux free. These preforms can be put in certain pads to increase the amount of solder … Continue reading

What difference between SMT (Surface Mount Technology) and SMD (Surface Mount Device)?
What are SMT and SMD? The difference between SMT and SMD is that SMD (Surface Mount Device) refers to an electronic component mounted on a PCB using SMT (Surface Mount Technology). What do we mean by “SMT (Surface Mount Technology)” … Continue reading
