Preheating pcb is used to preheat circuit boards that need to be repaired to minimize thermal damage, reduce heat demand on soldering tools, and thus speed up rework. How to use the preheating pcb What do I need to pay attention to after using the heating pcb? Preheating is a very important step in PCBA
A main pcb assy, often referred to as a collection of various electronic components and connectors that make up a motherboard (also known as a motherboard, system board, or flat board). The motherboard is the core component in a computer or other electronic device, responsible for connecting and supporting other hardware devices. Critical components of
Parasitic means that the capacitance was not originally designed in that place, but since there is always mutual capacitance between the wiring, the mutual capacitance is as if it is parasitic between the wiring, so it is called parasitic capacitance, also known as stray capacitance. Parasitic components are additional components created by the electronics in
VIPPO (Via in Pad Plated over) is an over-hole technology, mainly used in PCB boards.POFV is Plating Over Filled Via abbreviation, refers to the PCB on the over-electrical holes, in order to meet the needs of the soldering and over-hole internal conduction, the first over-hole resin plugging holes, and then copper-plated to cover the holes
