The one you know how to use, and that you can afford. I'm not sure that there's anything that is perfect. Some people like to use free EDA tools, some prefer to use tools that cost over $10k. The one that you know how to use, that suits your pur

The assumption that a HASL Sn63 PCB can be soldered with SAC solder paste is likely a bad one. The board itself is likely FR4 which can be damaged by lead free temperatures. The HASL finish isn't an issue from the perspective of it's makeup and actu

Oh yeah, I've seen this before! Generally, if the hole sizes are correct (including plating), and the PEMs are within spec, we've found that this is most commonly caused by insufficient support of the PCB during insertion. If you can eliminate supp

Kester makes a thermocouple solder: Alloy SN10PB88AG2 Flux "44" Core 58 Diam 0.031" I have used this to solder thermocouples to pcbs when profiling for lead-free temperatures. When done you can unsolder the thermocouple and reuse it again. This g

And there is always the argument of "get in and out quick", which is possible with high tip temps. I prefer to use a really hot iron, and do it quickly, rather than a lower temps and keep the tipi on the bit till it melts the solder. If you have a P

We were using TL1240Y Tack switches for 2 layered PCB and posted those switches by hand. Now planning to re-spin PCA where we recommend that part to be added on SMT process. So looking for a better and opt switch with same specs. Please suggest me an

Thanks for the support Jax. Our current scenario: Baking - Not allowed for PCBs Washing - Not allowed Heat Cycles - 2 (Bottom and top side). It's a notebook board Our concern is related to solderability because OSP finishing will be seriously imp

we received assembled PCBs with spots that look like a bleach spots all over the PS and CS . The board house said that this is normal due to flux aqueous wash process. Can it cause problems (e.g. corrosion ) in the long run or cause issues when wor

I'm with Evtimov...if you've got a new assembly with a BGA (and especially if BGAs aren't an every day occurrence in your process) it should definitely be profiled. I have run BGA boards without profiling before, and got lucky...but, I wouldn't reco
