Category:PCB Vias
A via is an electrical connection between layers in a physical electronic circuit that goes through the plane of one or more adjacent layers.In printed circuit board design, a via consists of two pads in corresponding positions on different layers of the board, that are electrically connected by a hole through the board.
Blind holes and buried holes are applied to high-density boards. Engineers use this design to save space of boards, so that reduce volume of the boards.(view more)
Via is one of the important components of a multi-layer PCB. The cost of drilling is usually 30% to 40% of the cost of PCB board. Vias can be divided into two categories: one for electric...(view more)
First, plug hole process after hot air leveling. This process is: plate resistance welding → HAL → plug hole → curing Disadvantages: Easy to cause plug hole ink pollute board. So ma...(view more)
Our ICT Guy here at my company loves to use lots of via holes as test points - via holes which are 0.040" diameter, and spaced at 0.004" edge to edge spacing! He doesn't like to tent the via's either,...(view more)
Can anyone point me in the right direction for information on this subject, my understanding is that it is a new technique, not in widespread use yet.(view more)
WE ARE EXPERENCING OPEN 8 MILL VIAS UNDER THE BGA'S, THEY ARE OPENING AFTER THE ASSEMBLY PROCESS, THEY ARE FROM MULTIPLE PCB VENDORS, THEY PASS AT THE PCB SUPPLIERS TESTING, AND WE HAVE FOUND THAT THE...(view more)
I was wondering how I would program the Mirtec MV-3L for through hole solder? Do I need to bring in the solder mask file? or can I do manually?(view more)
Diagrams and Schematics One problem with the smaller PCB drill machines is that the speed drops rapidly as the load increases. This can be overcome to some extent by increasing the supply voltage, ...(view more)
