Vick Russ is very correct. Get the paste material specificatioin. Please get your favorite data logger (ECD, KIC, DatPaq, etc..), attach some TC's and take a profile. This is the ONLY way to know what your reflow system is doing and how to alter.

We do both our ovens once a week. If something looks out of tolerance (we've developed acceptable tolderances based on many recorded profiles over time and oven mfg. specs.) we wait a couple hours and try again. The recorded data over time is very

All data loggers will be warmer at the higher lead free temps. Only two ways around this... better thermal barriers or fans after the profile to cool it down. Some places do not allow fans on the production floor due to static electricity, in that

A few lifetimes ago I went to a seminar on reflow profiles. The speaker emphasized more than once that the cool down rate is important. Someone asked him about controlling the cool down rate and he acknowledged that you can't. And IIRC it was an ove

I used to associate the mass of the assembly with the reflow profile. The greater the mass, the greater the quantity of heat you need to give the assembly. Most of the time you just need to reduce the speed of travel in the oven. Try different settin

sounds like a profile for some type of adhesive. depending on your required profile (manufacturer supplied) make sure that it matches it. For most adhesives (loctite, etc...) you just have to make sure it reaches a certain temp (150C for example

James, What type of profile are you using. Ramp-to-Spike, Ramp-Short Soak-Spike, or Long-Low Spike? I had a similar problem in a past life - random skews on chip components - and got rid of it by converting to Ramp-to-Spike (the old profile was R

In the fine SMTnet Archives, grantp gave the following response to a similar question: KIC supplies a free-downloadable software that "takes your profile data and recommends the best oven temperature settings and conveyer speed for your oven. The so
