The 1500 is rated for up to 300c. So it shouldn't have a problem with lead free right? http://www.petlock.com/data/Heller_1500_specs.htm

We have been using a Heller 1707EXL (7 zones + 1 cooldown zone) for lead free (ROHS) soldering since 2007 with good results. I wouldn't go any lower than 7 heat zones though. If I may brag a bit....The IPC-7095 revision C standard was released a fe

Can lead free components/assemblies be contaminated if reflowed in a reflow oven for leaded process?

I have only one reflow oven can I use it for both processes (leaded and lead-free)? If I do use it, one run for leaded and the next run for lead-free will that contaminate my lead-free process?

I don't think so. But I want to point out the amount of lead needed to contaminate a joint is microscopic. You won't have lead vapour in your oven and with a clean oven there probably isn't any other way for even a microscopic amount of lead to con

I worked for a company that had an industrial nurse come in and talk to us about lead and saftey. Basically she told us in no uncertain terms that we had nothing in the facility that would come close to producing the temperature required to have lea

Interesting... We had visitors from (maybe out of space) that claims that the fumes!!! from whithin the reflow leadead solder process in an oven can get caught inside the oven during time and later on when we fire up the beast to the lead free temp-p

Hi smtspecialist (man I gotta get me a name soon), NO! Your oven cannot contaminate your process. Unless you have flux residues dripping on your board, there is nothing to worry about. Now having your operators switch from leaded to lead-free smo

smt You should have no issue using your exsisting oven for both leaded and lead free materials if the machine is capable of delivering the desired profiles. One aspect that makes a "lead free" oven is the design of the system. Ability to reach th

I am seeing a problem of flux droping on the PCBA during reflow. This is a pb free process and I am using KOKI pb free paste with 8 zone (and some 9 zone) reflow ovens. Line throughput is about 10,000 boards/24 hours. I suspect that the exhaust is no
