I was asked how we verify that the thermocouples INSIDE the reflow oven are calibrated. That seems pretty impractical to me. Has anyone come across this ?

Hi, Essemtec and Mydata are big companies in the industry that manufacture machines . Manncorp is a reseller.

The two first level cuts at comparing placement machines are: * Placement rate * Range of component capabilities This boils-down approximately to machine price. Virtually, everyone's feeders are priced similarly. Go to "Circuits Assembly" magazine

The tendancy always has been "when in doubt, touch it up"... this is not the way to "verify the process" and is not the best strategy for multiple reasons (unessecary rework, additional labor costs, as well as making the solder joint more brittle, [i

Hege, there is no actual calibration of the thermocouple itself. You can however verify that they read correctly. Heller sells an option on their reflow ovens specifically for this purpose. I hoping that someone chimes in here that is NADCAP certifi

Mydata (recently changed name to Micronic) will be more expensive than Manncorp but from my experience using Mydata, they are well worth the money. Tech support (in the USA at least) is very good if you go through them to buy the machines. You can

My company is a low-volume high mix contact electronic manufacturer. We are currently looking at purchasing a pick and place machine that is capable of mounting such new components as microBGA's and other CSP's at such ball pitches as 0.5mm for examp

Paul, All the machines yulisted are very god at placement. One thing to keep in mind is parts availability. Some of our jobs come from the customer in "kits". Not everyone supplies you with a full real of parts. Be sure that the machine you pick

I did not question the accuracy, which is very good, but only 99.8 % of the time. If I require this accuracy for a certain part to be placed, than I want to have this part on target more often than 3 sigma permits.
