Dear All, Thanks for your help. I'm not clear that when you mention the number of zones of the reflow, says 8-zones, do you refer to the total number of heater zones (both top and bottom) without cooling zone? Hi Russ, the P&P model I mentioned is

Good morning, Glue printing and glue dispensing processes have their pros and cons. Speed is main glue printing process �pro�. A-n-y dispenser will be slower if you replace your DEK with it. Your placement machines do not wait, right? So I wonder wh

I was wondering about a bottle neck at the oven too, but apparently you don't have that problem. Are the boards small enough that you can put more on a panel? Other than that, it does sound like you need another printer feeding your placement machin

Dear Fastek. For the Front panel board we are using multible ( 4 boards in one PCB. even thought the balance between the DEK printer and the placers still big 6 sec as a difference. But, may be this is a good idea for the main board? may be also it's

You might be able to get a step up transformer although I would not recommend that unless it is a good solution for you. What is the input voltage to your facility? It is probably 600V (or something close). If so then you could get a step down transf

It looks like one oven is 10years newer than the other, so if we assume same maintenance routine you should get another 10 years if life on it. On the TH side, you know your board complexity - for me wave have much more value than a Selective. Selec

The ovens you're looking at need 100 amps of 480, 200 amps of 240. Do you have that extra power available in your building? You can go with a step-up transformer to convert 240V to 480V. My understanding is that ovens run more efficiently on 480V.

One thing that you do not want to do is run a 240V oven at 220V. One place I worked a few lifetimes ago had an oven that had five top zones and only two on the ends on the bottom. It was something like 440V but supplied with 408V. It took a long long

LOL! Good to know! Yeah, we have 3Ph with a high leg, so technically at 240V, so we should be fine. Since nobody has really mentioned a real preference with the ovens, is it kinda like what I thought at first? That an 8 zone oven is an 8 zone oven.
