We are starting to see issues with using Kester WS R562 with lead free components. The joints look grainy on almost all of the 0402'2 and other small components. Some of the solder does not solder to the terminations. These are hybrid boards which

You can keep only the 5th zone as the reflow zone. And lower the first two zones to keep a good ramping rate. Meanwhile,please note the ting temperature in software or control panel is not the exact temperature in your PCB, you'd better get a KIC or

Well, most of the capacitor are thru hole, then pcb's goes to adhesive process upsidedown to continue SMT process in which , maximun tempetarure is 120�, so temperature is not problem. About SMT capacitorS, I will check temperature specs before mount

Hi, Yes, I would hate to resort to cleaning, but the product must be clean. We have been using palettes to keep most of the flux off the PCB, but there is still residue around the connectors. Does anyone suggest a good no clean flux to use with le

Hi, I have noticed we are getting residue on our wave pcb's and it's worse with lead free, since we changed to the flux we are using. We are currently using Avantec VOC Free flux model Ecofree 303. It looks like it's made in Malaysia. Does anyone h

ECD sells the MOLE, and they sell both the Oven Rider and the Wave Rider to accompany it. The thing is, you can profile both an oven and a wave machine without either if you're willing to just solder your thermocouples to a board. The nice thing ab
