No N2. We could not fix a benefit for N2 in our minds. Just fold the excess bag material over to expell most air and then seal the bag. [Have you assessed the benefit of N2?] F Monette can tell you stories about little versus more pressure. If he

Hi Folks, This is a totally speculative, if not cheeky post. I know very little about electronics, but I think you guys do. I have a problem with my car radio, that I'd really like to solve, as I cannot buy a new one where I live (Brazil), and I th

Cannot comment on "best buy". You'll have to determine what the better machine is for your application and duration of planned use. I suggest taking a field trip to each vendor's nearest demo facility with a few of your most hi-tech boards and stenci

Bright ideas??? Bright ideas!!! I got bright ideas. In order of decreasing luminosity: * Stop installing the socket, solder the PLCC to the board, dip the board. The socket is a waste of time and money. You never replace the PLCC in the field, a

Hello Neil, I absolutely agree with the conclusion of limits as you have stated. There are 2 sets of limits in which machines can be measured against for compliant performance. First and most critical being the quality performance specification limit

Oh dear, I tried not to respond but i couldn't help myself. Stop me if I go off into the woods. My guess, Chris, based on your fleeting reference to GF files, is that your SMT machines are Siemens Siplace. If this is so then package orientation def

Observations are: * Center most lead of the fuse on the top right of the assembly looks like it has excellent solder flow, but this is PTH. From the amount of solder, it must have been wave or hand soldered. * Center most lead of the fuse on the bot

the reason you don't want to use PPM is exactly the reason you need to. You cannot compare a square 1" block to a multi faceted custom machine part. In SMT assembly you will usually find that all 0603 and larger discreetes,25mil pitch, etc. are pro

I want just to confirm what Dave suggested you. J-STD-033a, par 6. Boards Rework tells you plenty of useful informations. 6.1 Component removal, RWK and remount 6.1.1 Removal for Failure Analysi 6.1.2 Removal & Remount 6.2 Baking of Populated Boar

Grant, Again, just my .02 worth. I would have to agree with Greg as well. Two Flex machines from the same vendor will give you much better line balancing, and I think better overall capability than adding a different type of 'animal' chip shooter
