I always look at the support structure. This is where I feel the real Dollars and cents come into play. Sure you can calculate the derated value over months or years. But If your machine is in a "machine down" situation the derated value does not cha

Hi! Give training to SMT machine operators. Or do annual maintenance.

Machine design plays a major factor in actual placement rate vs. the published tact time max speed. For example, random access horizontal turret head machines can vary greatly depending on nr. of different components and size ranges, while the dual g

Hi Rob, I guess the ratio between chipmounter and GSM is very much depending on the chip to ICs ratio. This is product dependent. We use 2 HS50 to 2 GSMII, 5 S20 to 2 GSMII, 3 Sanyos to 2 GSMII, and 2 CP6 to 2 GSMII. Are these ideal ratios ? Lean Ma

Yes, it is most likely the BIOS and Windows Time configuration. If you are familiar with how to switch to Windows Operating system mode and back it can be checked. Our displayed times are off but in ASM trace service the times are all accurate so I d

Individual process steps are approximately the same length of time for reworking a BGA. You seem to be comparing the use of the automated SMT line versus an off line rework station. Consider that the off line station is a complete paste print, pick

Hey guys, so awhile ago I started working as a machine operator at a Siplace SX line (4 Stations: sx2(cpp) - sx1(cpp) - sx1(cpp) - sx2(twin head)) and i noticed a strange thing. The displayed times of the stations don`t match up at all, not even clo

Traditional methods of hand assembly are as you described. For a company that is concentrating on the 1-5 or 5-50 quantities you've described, you need to look for ways to accomplish your task with speed, repeatablilty, quality and at a fair price. T

If you allow 3 seconds for insertion of each connector and 2-3 seconds for each solder joint, then add a 10-12% contingency allowance you shouldn't be far out. Maybe get an averagely rated operator to build one on the clock. Regards, Chris

We have Vectorguard frames we've been using for about 6-8 months. We've seen no leakage on ours. The frame has written on it an operating pressure of 101.5-116.0 psi,our pressure is set a lot lower, 50-60 psi, as we also use another frame that can'
