Wave flux and profiling

Electronics Forum | Fri Dec 15 18:36:46 EST 2006 | Grant

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

interesting, not at all what we were told so yes lot's of contradictions comming from them, I have to say personally I've not beein impressed with there technical service of late, are they getting complacent I ask? it's strange they say it'll cause

EricR: Regarding "*** By the way, since we have used the Tin-Silver-Copper lead free solder there has been a strange liquid type chemical leek from the oven exhausted pipes." ... I don't know anything about your process, but the first thing I'd inve

01005 components and reflow profiles

you are seeing a typical issue that is caused when such small volumes of paste are printed....there are several reasons for it..the tiny amount of flux in the small deposit becomes exhausted much quicker then it does in a larger deposit ( the flux ma

Here are some answers to my questions after a good research. I also added more definitions that could help understand this esoteric language used in assembly, specially surrounding fluxes and their use. In blue italics are comments and extracts from

I would like to enter the discussion by tossing some numbers in. First of all I don�t like the 3 Sigma value. 3 Sigma are 2000 defects per mio. if I remember correctly. This means, if you have 200 components on the board, then every 10 boards have on

paste Sn42/Bi58 and Lead Finish

Electronics Forum | Fri Nov 02 14:46:18 EDT 2012 | ericrr

So how does this (lead free paste Sn42/Bi58) solder compare with the Sn-Ag-Cu (Tin-Silver-Copper) combination which does not flow as well (in the oven), needs higher oven temperature, (that can be adjusted by reducing the oven chain speed) and cost m

Time and temp in lead and lead-free reflow

Electronics Forum | Mon Jul 28 16:48:54 EDT 2008 | pcbbuilders

my oven has a built in profiler, it works fairly well, but it can not predict changes. my main concern was about the time right before reflow. i know that's where the flux is activated and i was worried that i may be spending too much time at the tem

The European WEEE has issued a new (5th) version of its recommendations. In it they say that , on January 1st, 2004, they will review the status of the Pb-Free issue. There is currently NO DEADLINE for implementation. As far as a direct replacemen

N2 is a reflow process widener so to speak, for leaded reflow less of a impact, for LF more impact, and if using finer LF solder pastes T4,T5 and smaller paste deposits generally, it helps widen window for flux in paste in oxide protection during soa
