How to calculate the delta T ? What's the allowable range for delta T value? we r not calculating this in our process, instead we r maintaining the pre-heat temp which we measure from topside of the bd. Thanks in advance

thanks for the feedback....but what's your delta T and how will you know that you are within the delta T range ?...I think this is the main point of the above topic...can you elaborate more on how did your company get Delta T ? thanks and regards,

I used to build the SMTech 100 range of machines before the company closed, and i also have dealings with them still. The 100is is a very capable machine and will go on forever with a little T.L.C. foxy

You're correct. The units should be micro inches. By the by, this gold always should be a hard gold (99.96%-99.97% pure) with a Knoop hardness range of 130 to 200 (optimum 170).

Help us understand how these two types of equipment compare, in terms of things like: range of application; types of problems they would be used for; cost in terms of purchase price, operation, facilities, etc; technical skills required; etc.

To piggyback on CAL's suggestion to provide date of posting, or maybe to be able to sort ranges, I also feel that it would be good to include a geographic sort to narrow down the possibilities.

Load Factor = Board Length / (Board Length + Space) (you can get the maximum loading factor from the manufacturer, usually ranges from 0.5 to 0.9) Oven Throughput = (Conveyor Speed x Load Factor) / Length per Board
