Thank you both ( Gnus and Phil) for the replies. I will try to answer both with a new post. I like the idea of the stock room splitting the reels but our reels are released to the floor where the Magload ( Kit building) area stores them and builds t

We are a OEM and growing pretty fast. The like the idea of setting up common components on the machine. It makes sense from a set up perspective. All of our set up is off line but the set up usually lasts longer than the SMT run so we have some spora

Thank you for the response, but the machine selection is not made by me, I only evaluate the machines. So two days ago I visited a company that has a Viscom AOI. I had good impressions about the machine but there were couple of things I didn't like:

I am running a product with board size ~18"X16". I faced stencil aperture positional accuracy issue which slightly shifted at both end of stencil at positive and negative in X direction thus causing solder paste to pad mis-registration. Due to this s

I have had Selective issues such as yours on two very different Selective Solder Machines. I was able to eliminate these issues by using Alpha EF-9301 wave flux with any SAC305 solder. It's a more aggressive flux, but really made the difference. Anot

Here’s what we seem to know: * There’s a problem with voiding in the solder connections of SMT capacitors * A void is an open area caused by air or process fluid that is trapped within a solder connection * Voids are an allowable condition as long as

Would like to ask end users or those with experience using infra red rework equipment (specifically when the top heater is IR) the following: 1. Can you successfully rework Package On Package (PoP) type devices? With heat directed through the packa

Hi guys, I need your advise on this, I have a very uncommon PCB design (at least for me, I've never seen anything like this...) it is 32" x 18" x 0.062" and has 9 QFNs that are driving me crazy, I'm not able to get a good alignment, I can get a mediu

I need help with how long do I need to bake out double sided PCB's that have been cleaned. The units will not be reworked but instead will be moved on to hand stuffing. I have looked in IPC CH-65B and J-STD-033C. I get information for parts if I am r

You might try to complete all your soldering within a 72 hour or less time frame. For all intents treat your board like a moisture sensitive component after you have baked and completed SMT reflow. Wash, blow dry, and go direct to stuffing and com
