We use an LM2575 switching regulator, and have had no trouble reflow soldering it. It is made for that purpose, so no big tab with the bolt hole, and the leads are pre-bent for SMT. Note that soldering the part to the PCB doesn't really give the he

Greetings, Does anyone know where to find a tape and reel flatness specification? Looking at the EIA 481-B standard, there is no reference to the tape flatness (the images shown may "imply" flatness from one side of the tape to the other, However I

Dan: OSHA is going to expect that you have a safety plan with lockout/tagout, blood bourne pathogen control, hazardous material spill remediation procedures, first aid preparedness, emergency flushing, etc. While not required specifically in the co

The owner of the company is from India, I don't know if that has anything to do with his thinking. He told me that he runs his business like a garden not a military. So I wear my safety gear and I am not too concerned with his fines as he appears to

You won't want to hear this, but I guess that depends where your tattoos are located, and whether you swear like a sailor around the company. It's perception and people will perceive you a certain way depending on your appearance and how you handle

If you go with MCS I would recommend using an MCS30. You would have to make sure that the E-Proms for host communication are installed in the MCS and the host module (software)as well. You would then need CadConvert to program and transfer programs

I had a similar situation with a very thick PCB (0.23") I could not get a TAL lower than 160 sec, I've spoken with my paste supplier about this issue and we have made some adjustments on the oven and we could lower it to 145 sec, I know it is higher

My program PCBSynergy can generate a file for this machine. http://members.iinet.net.au/~sarason/ The file seems to have a bug in the current release which can be easily fixed in a text editor. The use of the C comment /* has somehow got past me.

Not exactly normal, I don't think. Though I have seen similar in the CM world. I can't think of a way to remove that overplating, either. If you can't reject the boards outright, then you might be looking at some touch up work, should bridging hap
