A printed circuit board (pcb) mechanically supports and electrically connects electronic components using conductive tracks, pads and other features etched from copper sheets laminated onto a non-conductive substrate. pcb's can be single sided (one copper layer), double sided (two copper layers) or multi-layer. Conductor on different layers are connected with plated-through holes called vias. Advanced PCB's may contain components - capacitors, resistors or active devices - embedded in the substrate. A lot of our products get mounted on DIN rails inside panels. Most of the time, the PCB is designed to fit in a housing that is then clipped onto the rail. There is some additional circuitry on the underside of the PCB. The intention is to mount several circuit board DIN modules on the rail and connect them to the under-board circuitry. The board fits in a long plastic housing (which can be cut to any length) that protects the bottom of the board, leaving the top exposed. The housing also has feet that allow it to mount on a DIN rail. There are examples of the housing in several of the photos that follow. TS35 rail fits in the slot, circuit board which is vertical in this photo. This module doesn’t use a housing at all. It actually connects the ground of the PCB to the grounded rail by making contact with the screws that affix the foot to the PCB. For those of you intrigued by the square holes in the screws, this is a great Canadian invention (no slip and the screw stays on the screwdriver) called the Robertson screw. One of the most time-consuming activities in mounting modules on DIN rails is wiring each module. Since almost every module needs power and ground, circuit board the arrangement in the picture is a split TS35 rail with a PC board down one or both of the sides for bussing of the power, ground, and some other signals. The big spring-loaded clip in circuit board picture below is meant to hold a coax-type wire in place and simultaneously ground it with the external sheath removed. I believe this is normally supposed to be screwed directly to the metal back-plate in a panel. The picture below shows a dual socket US power outlet with circuit board ground-leakage mounted on a PCB.
If I may paraphrase words circuit board from "The Charge of the Light Brigade" by Alfred Lord Tennyson -- "Ours is not to reason why, ours is but to do and" well, maybe not die. More frequently than I like, we get asked to design something that makes no sense to us. Here are some designs that we circuit board were not sure should involve a PCB, but did.
This comprises a resistor and LED. It fits under a 5x20mm fuse. circuit board The fuse in this image is shown projecting out the back just to give the size comparison, but in reality it fits right on top of the PCB with its contacts resting on the large pads you can see at either end. The whole assembly clips into a fuse-holding terminal via a hinge. This is one of our best sellers.
There are times where we want to provide a visual indication on a board, but without any components on the user side (with the exception of connectors). In order to cater for this circuit board, all of the components (except the connectors and switch) circuit board mount on the solder-side and we use LEDs that allow for reverse mounting like the CMD91-21/TR10 from Chicago Miniature. I guess there must be an equivalent switch, but we haven’t found it yet.
Over the years, we have used some unusual components. In fact, we have even mounted analog meters directly onto PCB as illustrated as picture below circuit board.
How about unusual board shapes? circuit board Because of thickness limitations, there may be cut-outs to allow pots or other components to be installed in the housing. Also, the need to insert the PCB into the housing without removing the connector pins sometimes necessitates some unusual shapes as the picture show.
Our organization doesn’t have much in the way of mechanical engineering. circuit board This means that it is sometimes simpler for us to make something out of PCB material using the PCB tools rather than subcontracting it out for mechanical design circuit board.
Extending this idea, the four PCB circuit board are used to make the connector adapter assembly in the lower left. Only one board is used for electrical connections. circuit board The other three are used for a combination of isolation, spacing, stiffening, and finger-proofing.
We know that the board plays an important role in everyday life, of course, accompanied by a large number of e-waste generation, waste circuit board so it must be set aside to be thrown into a corner or trash it? Our answer is no. Here are some DIY Daren's unique circuit board works, let us enjoy it!
