thank you for the reply.....this reinforces the same info about SAC305 that i had reviewed in other papers. Since this is an inherent property of SAC305, i am assuming 1. Wave parameter (temp/time) tweaking will not mitigate this? 2. what is differ

Sheldon, Try using SN100C wire solder. It seems to extend the life of the tips plus solder joints look much better. We use both, clean and No-clean. We had the same problem while using SAC305... Thanks, George

Can anyone advice me on the effect of SN100C wave solder on SAC305 hasl board? I suppose the silver content on the hasl pcb would leech(contaminate) into solder pot.? Would it affect the surface bonding between copper pad and the solder.?

Is there a standard (IPC, JEDEC, JEITA, etc) covering the tolerances on percentages of Sn, Ag, and Cu in SAC305? I'd also be interested if there are standard allowable amounts of other contaminants. I couldn't turn up anything in a search of the IP

I can't answer for wave, but we tried some Sn100 paste for reflow, and couldn't get it to work worth a darn. I then got some SAC305, and was relieved to see it work almost as well as SnPb at its best! Much better wetting and flowing to the various

Does anyone have experience with using Pb-free SAC105? We are looking at the pro's/con's compared to a SAC305 process for a SMT operation. I have read it has a higher melting temperature. Specifically, we are concerned about a product we are developi

Hi, I would be interested to hear the outcome of your trials! Although, if mechanical stress is of concern, I would look at what is causing the stress and tackle that. I would suspect that any stress great enough to fracture sAC305 joint would do t

I think you're okay reworking with SAC305 but rework with SnPb will result in a SnPbBi alloy with a lowered melting point that may pose reliability concerns. As far as suitability of 58Bi42Sn goes - depends on your requirements.

We use succesfully SN100C on ERSA330 for about 2-3years. Pros: - price, - less dross comparing to SAC305, - some ppl say better mechanical durability comparing to SAC305 (depends who pay for "independent" studies) Cons: - higher melting temp so r

SN100C is being used by 95% of our customers over the SAC305. The main reasons are Cost big savings easily $10.00 lb, nice shiny solder joints good for quality inspection. Very few people are using SN100C in SMT Due to increased temperature requireme
