Additionally, surface mount pads are particularly beneficial for the design of complex multi-layer boards, where space optimization is critical. However, it’s important to note that surface mount pads may not be suitable for components that generate significant amounts of heat. The compact nature ...
NPTH concerns a PCB pad without metal plating in the hole. This pad is generally utilized for single-sided circuit boards, or these holes are used for getting on the PCB in an enclosing, and chicanes are got on through these holes. Ultimately, unplated holes will hold an area close to ...

Via holes are also called metallized holes. In double-sided and multi-layer boards, in order to connect the printed wires between the layers, a common hole, that is, a via hole, is drilled at the intersection of the wires that need to be connected in each layer. Vias are used for lay...
Display and LCD Boards –OLED, TFT displays. Audio Boards –For SMT codecs, amps, DAC/ADC chips. Any specialized SMT component can have a matching breakout board for easy interconnection. How Are Breakout Boards Manufactured? Specialized PCB assembly is used to mount SMT components onto breakout...
What are the types of protective coatings for PCB boards? Polyurethane protective coating: Polyurethane (UR) coating has excellent protection against the effects of chemicals, moisture and abrasion. Polyurethane (UR) protective coatings are easy to apply but difficult to remove. It is not recommend...
Double-sided pcb substrate The double-sided boards are printed circuits on both sides of an insulating substrate with a thickness of 0.2-5mm. It is suitable for electronic products with general requirements, such as electronic computers, electronic instruments, and meters. Since the wiring density ...
Circuit boards are at the end of that range but the concepts do carry over. You’re mainly stitching together IP blocks with vanishingly small features. Of course, this job has increased in complexity over the years. They still need new people to join their ranks as the OG experts retire....
(break-away, coupon) to serve as markers for testing fixtures. In the past, these NPTHs were also used to hold the PCB in place during SMT process, but nowadays, most SMT machines use clamps instead. However, for thinner boards, NPTHs may still be necessary to prevent deformation during...
Gerber files are now a standard to follow for the mass production of printed circuit boards, as they show the exact graphic description of the PCB. They should be sent to the manufacturer as soon as the project is completed and has been thoroughly checked. The designer can safely send all ...
