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.

THese you can have single or dual head, long for a lot of feeder positions, with bigger or smaller work area based on your needs. Feeders concept is very clever and setups are quick. A lot can be done on the fly on the machine, compared to other bran

Hey all, I've made a post in the past about us expanding to a new space, but I wanted to do a new post with specific questions. We currently have a DEK 265, Phillips Opal Xii, and a Heller 1500. Our main reason for expanding is to have a lead-free

Hi Guys, Sorry for asking stupid questions. Are SPC, PPM and DPMO related to each other? Do they affect each other then? What is their inter relations? Can someone explain to me what are their purposes? thanks
