Reflow oven profiling - frequency ???

Hi there, in my factory we use profiling every temp. change or once per day others make 1 profile for machine per week what is safe in your oppinion to be sure that all products made are good :) or if 1 per week is enough how to prove it to bosses

Good afternoon, We develop reflow profile ones and control it daily or when recipe changes after that. Modern reflow ovens are usually very stable. This means that your zone temperature set points won�t deviate from initial ones. You can calculate d

Hi, We run a profile check each time we load a recipe. This ensures that the correct settings have been used for the job. It also gives traceability in the event that you need to prove whether or not the oven temperature was the cause for failed pro

Pavel is right...Your Quality Group, customers, and Management will really appreciate Cpk's. We do Cpk's annually, or whenever a major mechanical change (motor, blower, etc) is made. Pavel is correct in saying that Cpk's on most modern convection o

Hi D0m0 Can you standardize on your temps and just adjust conveyor speeds for various sizes of the boards? Another trick is to parallel t-couple plug off the actual t-couples of the oven and mount the plug in an easy access point of the oven. The

Profiling is product specific. An instrument called the OvenRIDER from ECD is for soldering machine quality management. See link below. This instrument measures various parameters of your oven to include thermal transfer efficiency. The concept is,

If your product mix is similar in terms of thermal mass and componentry, find some standard setpoints (by doing a baseline profile) which will produce a thermal profile that's within the specs. of your solder paste and product. This approach usually

We are currently using Oven Rider (ECD) to "verify" just the conduct of the peak temperature; we define which product is the higher runner for this line and then with the settings for this product (already profiled with thermal couples attached to th

It always surprises me how many variations there are for profiling and controlling your ovens, and the thing is most of them are fairly valid. Here's yet another option: Your board profile needs to be specific, 2 boards can look identical but have ve

Anyone have experience with Indium NC-SMQ92J solder paste used in an inert (N2) reflow oven?
