Hi, I would be interested in the data, and I after our experience with batch convection I am quite skeptical. I would be very interested in temperature plots. What I would like to see before I ever considered a batch convection oven is how the oven

Samsung SM320 don't have sensor for recognizing component. Only using Fly&Fix camera. In first time the korean samsung service engineer advised me (3,7light settings for chips and the machine generated many dumps, sometimes 50 or more per day. But n

What you are most likely dealing with: Insufficient Pure Sn layer ( multiple causes ) Because elevated temperatures accelerate the diffusion process, the thickness of the Pure Sn layer will reduce during every thermal cycle... ( bakeing PCBs, S

The ramp sets the stage for flux activation, and if ramping in a linear fashion, burning off some of the volatiles, but yet preserving the activators. The ramp is also intended to preheat the SMDs to prevent thermal shock. Most solder paste data sh

Thanks for the input Guys Yeah the not so knowledgable customer does not like to residues for cosmetic resons. The flux is for lead free process, of the no clean and water soluable type. We have explained to him that technically the residues do not

Okay fellas...I posted awhile back regarding CP4 and CP6 placement issues. I think we may have figured it out. XO/YO and mark read positions were not correct. However, we have a new problem with the CP4-2. I was running the Fuji board, placing a s

Sorry, I have not read the article. However, I do have five years experience constantly tweaking an AOI system that ran ONE product! The strength of the machine was solder inspection. The biggest problem was component color variation and shadowing

Hello Brad, We are running the Slim Kic 2000. We have found the predictions to be fairly accurate as long as the suggested change is within 20 degrees of the original recipie. As a test I ran a board with the wrong profile. The predictions got me wi

I don't know about industry standards - I suppose it depends on your equipment, really. We are low-volume, high-mix with many, many part numbers. Here's what we do and we have pretty good luck with it: Over-issue parts to kits; 10 over on 1206's,
