Grant, The only thing that you really gain from refrigeration is a couple more months� shelf life. Refrigeration also seems to slow down flux separation. I am not sure how your paste consumption is, but we use ours up way before the expiration date

We have an YXLON Cougar X-Ray machine. Run good in 10 years. Now, when we started the machine as usual, the machine run START-UP process, Manipulator Reference OK, Vacuum OK, but not "Warm Up", the X-Ray keep turning off and on showing Voltage ~50KV

Ramp or Soak give us same Deta T (from 35 to 40).All probes are tested o.k.Should we pump in more heat upfront in order to warm up heavy loaded ICs like PLCC64 or Change blower speed? or Slow down line?

Heller 1500W running on Windows 95. Warms up fine but the belt speed will not adjust. Running very fast and will not slow down when adjusted. Anyone ever seen this?

Hello Everyone, I am having a pin chain speed problem. The speed of the chain will slow down after start up of the oven. Example if you set the conveyer to run at 41 in/min, as the oven warms up of conveyer will slow down phycally but won't chan

Good Morning, I have a Phoenix PCBA Analyzer 160KV with NanoFocus tube. The machine warms up till 104KV only (it gets some breakdowns around 100KV) and then it finishes warmup but doesn't go beyond 103KV while doing inspections. HTG Cable has been gr

Check the areas that are getting solder on the top side. If you have internal ground planes, and the ground plane pth's are not getting solder on top, and signal pth's are, it's a heat problem. If the ground planes are in the middle of the board yo

No question that metal retains a lot of heat (slow to heat up and slow to cool down). But again in a batch oven, it mainly boils down to the heater. I know, until you see proof you are skeptical. I think by posting a url to product specs will

| I need some advice concerning reflow of a BGA-292. Since I am not ready to change my entire process to no-clean, I decided to place the lone BGA-292 on a proto run using our BGA re-work station. The pcb is a moderately dense, single-sided, 8-laye

If the flux you are applying by brush is alcohol based, use some alcohol on a few failed PCBs and retest. It souldn't take a lot of flux to reflow the balls to a pad that's already covered with solder and flux from the first BGA - unless you are cle
