German laser specialist LPKF has developed and patented a plastic that can survive reflow soldering and which can act as a single-layer PCB. The company's polyimide material is impregnated with a ...

I needed two-layer 1 mm thick black PCBs, but I wanted like 50 of them where economic assembly would only allow 30. On this board, having to use “standard” assembly would be a significant ...

[Petteri]’s design delivers 3 mA to each of eight surface-mount LEDs (which he says is actually a bit too bright) for a total of about 20 hours from one alkaline AAA cell. The single-layer PCB ...

In this three-part series [1], I discussed PCB layout considerations for fast-switching DC/DC converters using a step-by-step approach. Steps 1 and 2 from part 1 examined the PCB layer stackup and ...

Layer 1, or the top layer, is described as a signal layer. The 0.0014-in.-thick layer is made of copper material; the copper amounts to about 1 oz. These parameters are valid for a board whose ...

It’s all put together on a single-sided copper PCB that [timonsku] routed at home. “The goal was to show how little you have to do to do a fairly feature rich carrier board for the Compute ...
