Hi, For the past few weeks, we been seeing solder hole after reflow and this product been running for almost a year. We had try to shorter and longer the pre-heat time, reflow time and even reduce and increase the temperature....but could not help..

This RoHS has created a new "underworld" of brokered parts --- parts dipped in Lead-Free alloy to pass as "lead free." I could see some guy with a fur coat and feathered boa hawking lead free parts on the street: "Check it ouuuttt...I got lead free

Are these covers repacements for the tape guides? If so in retipping many thousands of cp6 nozzles we see that the window in the tape guide is often miscentered and the needle tip rubs on the same place every time it picks. I expect the miscentered g

Hi all, We are starting to see more and more 0402 components on BOMs of late. We have a small quantity of feeders at the moment which are 8x2 paper. Any 0402 components we have placed have been on these feeders. I noticed that you can get embosse

I would be interested to see what Dross eliminators are available also. I am currently trialing a very user friendly Solder Saver Handtool- it basically churns the Dross Solder until the dross is left in Powder form. We then scoop out the powder. e

We've just conducted an MS2 study, and we found very little improvement. We run N2 inerted contour waves (E-vert). It seems that if you use N2 and a dross reclaim agent (Kleenox) then you may not see as much improvement. What types of waves are yo

Well my friend, flux chemistries have changed. I do not want to drive you over edge but I use a straight ramp for lead as well!!!! Let the product dictate process!! I only soak when the delta T is not manageable with straight ramp. Please do not

We are using Alpha UP78, which has generally good SIR values. We are seeing current jump from around 6 micro amps to 60 micro amps in a very small percentage. This does not seem to be likely with just ions immediately after reflow. The current would

Hi, Hope your machine is back up and running. Are you sure it is not program or PD (part library) related? Try power off and back on and delete the machine program from the machine. Then- Power off and back on and see if the VP error is gone. It

I think cyanoacrylate is the glue of choice for buna-n, but in a drive application with constant flexing I can't see how it would last. A longer (diagonal) joint is a lot stronger than a butt joint, but that would be even more prone to breaking if it
