This is an interesting dilemma you have been faced with. If both machines are outfitted similarly and running under identical process settings then they should produce nearly the same results, in theory. I do not dispute the observations you are re

OK, granted, this is not exactly your hi-tech SMD production but pertains to lead-free so I'll post this anyway: Can anybody share their experiences on lead-free dip soldering of transformer terminals? I have not done any testing myself but have see

Hello, We currently have huge quality issues with our Inertec selective solder machine, the model we have does not pump solder, rather the solder bath is raised to the product. We have continuing issues with bridging and non wetting of joints. We a

A little more information on your current wavesoldering process would be helpful in helping you. Information like what kind of flux your are using,how you are applying the flux,what preheat temps you are using,and your conveyor speed. Without knowing

Hi Eng. Yumex in our company we're using 9 zones air convection oven. When the technology on Lead Free came along conversion from non-lead free to lead free viceversa was frequently done but there's no problem on contamination. Where is your company

If the goal is selective soldering (not to raise the substrate temperature too high), consider the use of microwaves. Our company has been working on this technology for selectively bonding substrates. For example, we use the process to bond ROHS met

Hello, The answer to your question depends on your using a point-to-point system, or nozzles. Some companies might use 3mm as the nozzle wall width. There are many approaches to selective soldering, depending on your desired cycle time. I can g

My company is doing a project with a lot of QFN. The question that we are not sure is how to properly solder a QFN on a PCB. QA says The alignment tab on the side of the QFN should have a physical solder from the board, like a leaded chip. After refl
