Cost and time efficiency –the lack of custom fixtures ensures the process is not only cost-effective but also faster. This particularly favors low-volume productions and development. Flexibility –the movable probes can gain access to numerous test points on the board. This ensures that the flyin...

An old friend here I know you have the experience to help me solve this problem I have a few HO, DC diesel locomotives. There is an AC/DC train transformer that provides 3-11DCV power to the tracks. In these locomotives there only a simple light board that supplies DC power from ...
The respective manufacturers make the parts. Then shipped to the assembly line for placement onto the printed circuit board after checking them for accuracy. One may partially assemble these parts during the shipping process. They can still require further work before you place them into position on...
The best process to use would be a direct power iron combined with a convection pre-heater under your board. Without ... Reflow BGA's with CSP's There are two common solutions; one would be to apply solder mask over the open vias, and the other is ... ...
MOVs or metal oxide varistors are devices designed for controlling mains switch ON surges in electrical and electronic circuits. Selecting an MOV for a
The inverted F antenna, among the most popular in the practical applications, has a cheap design cost however raises the certain volume when used as the on-board antenna. Typically, the antenna gets mounted on the PCB’s top layer. Its floor is often situated close to the antenna on the ...
The manufacturers make tables, slide-rules and calcu- lation programmes available where the ultimate current selectivity values of Is under short-circuit between dif- ferent combinations of circuit-breakers are given. These values are defined by theoretically integrating the results of tests carried out...
This brings up an interesting question, how good are PCB manufacturers at actually meeting their specified tolerances? Established manufacturers work very hard to do so, because they don’t want to pay the high cost of scrapping boards when a customer discovers a problem. ...
technique can be used at the device output. According to Mathews and Toroni [6], this procedure should help identify bad ICs or other problems on the PCB. By focusing on the health of the low-side input diode of the DUT, this approach may eliminate the need to power the board for ...
