Ha-ha-ha-ha-ha,me lad. Wave solder is like an onion, it's got many many layers. Kind of like me-self. I'm a big ogre with many complex layers. At any rate i like the other colleague with his adverstising trigger finger. by golly, me chap, he's a

Hi, I am experience problems while testing wave soldering SMT components that are glued on the solderside (lead free). Between de leads of SOx type IC's and SOT's develop a great deal of solder beads. I have been using a RSS temp.profile while spr

Sounds like possibly too little preheat. Russ

Hi, I have a lot of solder bridge in our wave soldering process.We use SACX0307 and Surf 11 flux.the SW mashine is Vitronics delta 6622.Itry to change flux and termoprofile but results is not god.Can you halp me - recommend me some flux or other adv

Thank you all for your input. The MF300S Multicore flux is rated for lead free. There is not much dross or contamination. We are using nitrogen. I've tested the boards with the curing test of IPC-TM-650. I think you're all right about the preheat.

Blew chunks - thanx for thinking outside the box. Of course there's two sides to every story. Just last week I had a new operator "splash" a couple of boards. Top solder was great, it was all one big solder bridge. Come to find out, the operator forg

MF300S is quite an old flux, & a lot has happened since then on the flow solder front - are you sure it's designed for Lead free, or is it just a traditional flux that SHOULD work OK with Lead free?

Sounds like your flux to me. Since you cannot change the board or the machine, changing flux would be one question mark you could take away with a phone call and a sample. You will really be surprised how different fluxes can affect your final prod

You are right, RSS profile is not the correct description. I am using a profile which heats up quickly to let the flux spread. Next linear up to activate the flux and prevent thermoshock. My experience is however, that small changes in this profile
