Regarding your comment "technology doesn't seem to have improved". Actually, technology has improved significanty. Cyber Optics uses a line measurement, a new unit from Germany uses sine wave differential measurement. The Gridmeter unit captures a vi

It sound you have already discovered to root cause, flux entrapment in the via holes. Short of changing the desing, here are sone suggestions. The main thing is you have to dry out the via holes of the wet flux. Some things to try are: slow down t

Yes, it is quite common. Does it [refraction] provide adequate resolution? => Depends on: * What you mean by �adequate�. * When during the process [cleaning solution life] you make the measurement. Is the [refraction] measurement affected signifi

This SMT process certainly makes a body want to win the $$$ and retire! We have been trying to stabalize the process and keep running into new problems. Any help would be appreciated on this issue. All pads on both sides have the same look - partial

For an accounting standpoint, there is nothing you can do to affect depreciation, aside from selling the machine, as mentioned by a previous poster. From a physical degradation standpoint, there is nothing that you can do to stop operators and techs

While we have nowhere near the volume you do we have bent 2 A-14s in 3 years. One was definitely operator error in that a tape holder arm was left floating the other is unknown as this particular (ex)operator wouldn't admit to knowing the time of da

It�s up to you what and how you perform. I was only wondering how your figures match with todays performance efforts and predictions made by the industry. The stress today is obviously on change over times and concepts to minimize this time especiall

I wished, I would get a job like that. Malta is a nice spot! With 1500 Cph you can select any machine on the market, but here are some questions. If you use a glue machine you apparently deal with mixed technology boards. If your volume is that low,

The CP-65E handles a wide range of board sizes, including large boards up to 508 x 457 mm or 20 x 18 inches. Handling consumer as well as industrial applications, this durable and highly efficient machine achieves a cycle time of 0.12 seconds/shot an

Thank you all very much for the responses. The solder is eutectic and the problem, as far as I can tell, has been around before I was here, 2+ years. The flow machine is a treiber with 2 bottom preheaters and 1 top. The solder pot temp is 500F +/-4F
