In order to reduce the size of a PCB, I will probably have to use smaller SM components. I currently use mostly 0805 passives, and am thinking about going to 0402 or smaller. Apart from power dissipation considerations, any pitfalls I should be aware of when making the transition?
I believe I have heard of putting a plugged via right next to a mechanical pad so that the board is stronger there. But I’m not sure what the implications are for putting a via on the pad?
This question is about the advisability of continuing to use a USB mini-B right angle surface mount connector in my pcb designs. On occasion we see one of these connectors peel back or delaminate off the pcb. Immediately the question is asked, why didn’t you use a through hole connector?
I am getting a PCB manufactured for a project that I am working on. One of the parts, the A4950 motor driver, has a “pad” on the bottom, which is meant to be soldered to GND of the PCB for thermal dissipation. I was thinking about the prototyping, and I am unsure how I would go about (using a soldering iron), soldering the pad on the bottom.
I recently ordered some PCB bits from a new supplier to assemble a widget. I want to make temporary connections between different PCBs, but am not convinced I want to solder and then desolder and resolder wires while I am testing and prototyping. Is there any tips for doing that?
I’m designing a two-layer PCB and I’m very inexperienced. A third-party company will fabricate them. Now, I have a PTH part with a number of closely spaced pins. However, I can’t greatly simplify routing by running traces unless I eliminate the pads for certain pins on one side of the board. So can I leave a through hole pad off one side of a machine-fabricated PCB?
I’m using some 0.1% precision 10k and 150k resistors. They are thin film 0603 surface mount. For a lot more, there are also thick film types. Fundamentally and practically, what is the difference between these two?
Some online tutorials about soldering TH components, like transistors and ICs, are delicate components and can be easily damaged by heat. When it comes to soldering surface mount IC and components, some prefer to use a reflow oven which heats up the them to a temperature above the melting point of solder. So why?
Every computer PSU I’ve taken apart uses through hole components, though occasionally (not in all cases) surface mount components are found on the bottom. Don’t these have to be hand assembled? If so, why are they still doing this? even though labour costs are low in China, it still must cost less for a machine to pick and place SMT stuff.
