Hi Jay, please let us know your inputs from the seminar regarding SN100 Nihon solder from FCT. This solder seems to have a higher melting temp of 221C. It prints well and visually looks similar to SAC alloy. Have no reliabilty data though. Jay

Ther is a solder alloy out there that is supposed to allow lead free wave processing without having to upgrade pumps and such or increasing the pot temp (direct drop in). I have not used it nor do I plan on doing leadfree wave soldering but you may

Yes there will be higher process temperatures on the currently preferred alloys of tin/silver. There are not that many companies highlighting they have the solutions although many parts will be fine. If all components meet the requirements of the IP

Hi Scott, My Heller is a bog standard Heller 1500 with an edge guide. There is nothing special about it. I would of course love to have a 7 zone oven, but...I have to use what is here at this time. My only concern with a 5 zone oven is the change i

Currently we are using a 2 step vapor soldering process to manufacture our std. lead soldered parts. The first step was done with a ls240 vapor fluid and the second was done with a ls200 fluid. Using a 221 deg C sn95/Ag5 solder for the first step a

Do you think the impelers made of galvanized steel can support the hi temp atmospher for lead free applications ? If you think so please contact me I have a lot of thing to show you . hyabro

Hello Sir, Thanks for your reply. i just got a mail from the DIMA service group and they said the Oven setting is as follows: Max temp settings in each zone (Which is not the temperature on your product, but close to where the air flow comes out of

Depends on your specific application. Can you handle lower reflow temps? Can your parts handle higher reflow temps? What environment will your assembled product have to endure? Lot of different factors come in to play when choosing the right allo

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

Thanks. I will turn off the machine activated cooling and have the part cool down at room temp (no compressed air cooling). Can you recommend a good paste / tacky flux?
