Hello We are working with inspection Omron machine (VT-S730), we have cycle time problems with some models. Does anyone know why this happens? Months ago, the cycle time was fine, but now it is so high and our production is less. Thank you

Hello! Anyone here knows is there any specific time frame (production time control) defined for a PCB assembly process completed SMT? How long need to complete the SMT process if double-sided SMD boards are assembled?

Hi Sal, taking the dwell time as parameter to control seems to me unessary. Dwell time is a function of other settings that can be controlled (adjusted) more easily (conveyor speed, wavehight-settings, angle). Although dwell time is essential it�s I

| I am interested in seeing how some of you calculate machine utilisation. Currently this was calculated off against the uptime. I really believe there is a better way of doing it i.e if I were to calculate this against machine's capacities. Any feed

Places to try are: * Most BIG-time manufacturers of SMT production equipment supply promotional vids to their potential customers. Consider contacting them. * BIG-time SMT training course givers may have suggestions. Contact: EMPF, Texas Engineeri

Hi: I am wondering what others are doing that use a Static Ionic contaminate test (e.g. Ionograph/Alphametals) in relation to time. Our Ionograph has the option of setting a test time, or setting it to auto-terminate when there is no change in resis

Over all time will be dictated by your conveyor speed. Your conveyor speed will be dictated by your products time above liquidous. Time above liquidous is dictated by the manufacturers specification. Time and temp before reflow will have to be ach

If you define cycle time as the time it takes to complete one board it is a useless number. What you need to know is the time it takes to complete one board and start the next board. This means first fiducial on first board to first fiducial on th

Yes, it is basically: Rate = Time interval/Cycle time I put time interval since you can measure however you want (pc per hour, per day, per quarter hour... it is relative) the most used is Pc/Hour, so the time interval is 1 hour (3600 sec). Lets sa

Just a note, on fixed galden machines yes the way they compensate for rise time is as the previous post suggested, change power and also stage the lowering of the PCB into the vapor cushion ie not the main one but further up in the tank. The disadvan
