I'm with Evtimov...if you've got a new assembly with a BGA (and especially if BGAs aren't an every day occurrence in your process) it should definitely be profiled. I have run BGA boards without profiling before, and got lucky...but, I wouldn't reco

They are both very good machines however Kohyoung will give you better first pass results meaning a lot less false calls and when you run the first board after initial programming you have to fix very few things. However the cost is a lot more. This

Your solder paste manufacturer’s profile is just a “guideline.” You can customize your profile to meet your product’s need. For better grain-structure (shiney-ness) try a ramp soak spike profile keeping your preheat temps very low before your reflo
