But the manufacturers of the solder and flux you're using should have H&S data sheets that tell you definitively what's in them and what precautions are actually required. If you're soldering a lot of boards then nobody is going to suggest - especially on a public forum - that you shouldn't have good ventilation. But none of them are quite as nice to work with as tin-lead solder, which of course is why we used it in the first place. I prefer others which require a bit more heat but which do flow much more like tin-lead. Some melt at a slightly lower temperature but have all the flow characteristics of toothpaste. I may even add the solder tip extrator too the soldering iron too as they are only £24 extra.Īny other suggestions before I make a decision?Īnd圜_772 wrote:There are several different lead-free formulations. The BVX-100 looks ideal for what I need and sounds like it does a good job - after all the last thing I want is something that does half a job, then I get to 30 and find out I have done some long term health damage from toxin ingestion! It seems a little pricey from Farnell / Newark at £320 + VAT but if it does the job it is worth it. I like the idea of the attachment to the soldering iron but just wondering with it being so small how useful it actually is. My main concern is the flux and lead even though I try not to use leaded it is so much more pleasuable to work with when no regulations/standards have to be met. I use liquid flux, melt plastic PVC insulation off 30awg wire (so perhaps some toxins in that?), I sometimes use leaded solder too, and that is about all I can think that causes fumes. so really the only area that needs extraction is the small 40cm area I will solder in.
The desk will be lined with etching tank, pillar drill, shears, my own made PCB worktop with 2 soldering irons, hot air gun etc.
All simple single layer brick on the outside of the building so easy to mount things to walls, roof, outside, inside etc. If you provide some answers, I'll try to be helpful.īasically I am in the process of finishing my extension workroom that is 3.6 meters long by 1.5m width, so I have a 60cm worktop 3.6m long with a 2.5m roof. At the other extreme, you could work in a glove box.ģ) What do you mean by "fume extraction"?Ī) What are the size and composition of the particles?Ĭ) What, if any initial velocity do they have?ĭ) Are they mixed with a gas that's of different density than the room air? (The difference in density can be due to any of several factors, including chemical composition and temperature.)Į) With what efficiency do you need to extract the fumes?Ĥ) In which direction do you want the capturing airflow? The obvious choices are upward, rearward, and downward.ĥ) To where do you want to extract the fumes? For example, do you want to filter the fumes from the air and return the air to the room? Do you want to exhaust the air with the fumes to the outside? Each approach has advantages, disadvantages, costs, and regulatory concerns. There are several things you'll need to determine before anyone can provide specific guidance, including ġ) For how much of the ~2 square meter area are you looking to provide fume extraction?Ģ) How much convenience are you willing to give up for protection from the fumes? At one extreme, there's your present practice.
