The Company just certified to AS9100. One of the minor observations related to the method used to measure the lead length to insure compliance with IPC requirements. Are there any tools/devices/equipment available to measure lead lengths that is repe

Hello, I am not sure what you mean exactly. Lead length is something standard given from components supplier. Pretty much all new AOI machines can measure the length and height of most of the leads on a IC.

If you happen to have the Solder Paste Height Measurement System, it would able to do the works for you. That's only if the leads are not long.

I have been requested to explore the possibilities of using an inline lead trimmer in our manufacturing process. I have a few questions I need answered. 1. Can anyone recommend a good model of trimmer for in-line use? 2. We do double sided SMT,

I have done this in a past life. In my mind this is a step backwards. If all of your parts are placed by hand it will work.You will need to cut at the top of the solder to keep the leads form bending If any parts are auto inserted you will need to c

There are two profiles available for the Pb-free process: (1) RSS and (2) RTS. In your case, you should try a solder paste that supports RTS profiles. A minimum of 7 zone Refow Oven would be fine on the Pb-free process. However, you may still try by

As others have said, you'll have some difficulties getting good reflow on pb-free out of a 3-zone oven. We did it with a 4-zone for awhile, but only had really good success on low thermal density boards. That said, you should definitely check your

Hello, we keep having new individual tools for trimming TH components to the right length. Does anyone know where I can find a more universal mechanical tool that covers multiple component pitch and sizes? I am interested in buying such a tool.

Mike, Russ is right, no 'normal' wave machine will solder PCB's with 1" long lead length. I have seen waves modified to clear up to 5/8" leads, but the deeper the wave the uglier things get. They get uglier in that a lot more dross is produced, con

Mike, It sounds like you have a serious problem, I don't know much about drag soldering or what your specific soldering problem is with your present supplier. I do know that with a conventional solder machine these leads won't even make it through
