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 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

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

I run the same profiles for Top and Bottomside assemblies for all of my products. Only in rare instances have I been forced to run a profile with cooler bottom zone settings. This was obviously driven by assemblies with heavier components on the bott

Back-stepping a bit. If a profile is being used to: * Set-up the oven for a new product or trouble-shooting process, the profile should be taken with a solid contact to a solder connection. * Monitoring on-going stable and in-control process that re

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

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

Presumably you're talking about lead free, but you don't say. Heller can probably provide you with a starting point, as rob has already pointed out, but you do need to develop the capability to perform profiling yourself. That oven should have ECD

Setting up a PCB washing "system" and the facilities required for a cost effective and repeatable cleaning process depend heavily on the application (water soluble versus chemistry cleaning), (batch cleaner versus ln-line) and local factors (quality

If you can divide your boards into different categories it allows you to determine a different starting profile for each category, based on size, # of layers, etc. When you get a new board to profile you'll have an idea what settings will get you clo
