What is a PCB used for?
Printed circuit boards (PCBs) are used to mechanically support and electrically connect electronic components using conductive pathways, tracks or signal traces etched from copper sheets laminated onto a non-conductive substrate, employed in the manufacturing of business machines and computers, as well as communication …
How do you use PCB points?
Using PCB Design Tools to Assign Test Points to Your Board Once the parameters are set, the test points can then be added automatically or manually by the designer in an iterative process. Test points are typically assigned first to any available thru-hole pins and then to vias.
What does Y mean on PCB?
Y crystals. The serial Numbers of R107, C118, Q102 and D202 are often seen on the circuit board. Generally, the first letter identifies the device category, such as R for resistor, C for capacitor, D for diode and Q for three-stage tube.
What do the letters on a PCB mean?
On a printed circuit board, I see lots of tiny letters and numbers. Is there some kind of standard that dictates what letter indicates what type of component? The technical term for the markings is “reference designators” (aka “refdes”) and there are a few standards can define them.
What do you need to know about PCB basics?
1 Solder jumper – a small, blob of solder connecting two adjacent pins on a component on a circuit board. 2 Surface mount – construction method which allows components to be simply set on a board, not requiring that leads pass through holes in the board. 3 Thermal – a small trace used to connect a pad to a plane.

What’s the difference between flexible and rigid PCBs?
Flexible PCBs. Unlike rigid PCBs, which use unmoving materials such as fiberglass, flexible PCBs are made of materials that can flex and move, such as plastic. Like rigid PCBs, flexible PCBs come in single, double or multilayer formats.
