Continued from previous page During rework, it is important to use a
good, fresh solder alloy and flux. In this case, it can be tricky to know if you should use what is already on the PCBA or not. In sev- eral cases, it can be almost impossible (if not expensive) to discover. Weller offers both ROL0 and ROL1 liq-
uid flux to be used to prepare parts to be reworked (crucial in hot air applications), as well as different types of lead-free soldering wires, with L0 or M1 flux. They are available in tin-copper, tin-silver-copper and tin-cop- per-nickel alloys. When discussing flux and soldering
alloys, it is important to use a good filtration system because, during rework, the amount
of fumes generated typically is greater than in standard solder- ing applications. The parts involved could be dirty, coated with resins or glue, and may even need additional flux in the process. All of the above can potentially create dangerous substances that must be kept out
EPLAN Adds Expedited Request Option to Data Portal
SCHAUMBURG, IL — While the EPLAN Data Portal offers device data for millions of components, it can happen that the required device data isn’t found on the portal.
Users have had to create or
modify such data themselves until now, which is time consum- ing and sometimes cost inten- sive. With the new Data Portal Request Process, users can now hand this task over to EPLAN. This saves a lot of work for creat- ing individual device data and ensures the receipt of correct, standardized data. If a user working on a proj-
ect requires device data that isn’t found on the portal, they can send their individual requests for creating device data to EPLAN. The credits required for this
are directly shown, and the user can then use their credits to draw the corresponding amount for each query from their quota. This saves on frequently cre-
ating procurement orders and is transparent as regards potential inhouse cost limits. An EPLAN team creates the required device data within a few days in accor- dance with the Data Standard. Contact: EPLAN Software &

of the breathing zone. Weller’s three-stage filtration systems
can help with this. One stage is available as a “tip extractor” that has a small tube to suck up the fumes close to the soldering tip. Another is a “volume extractor” with a flexi- ble arm that can be set near the work area and covers a much larger surface compared to the previous. The third is an old-style sys- tem. Also, it is mandatory to check and replace filters regularly: main ones at least once a year or when the units alert and more frequently for pre-filters, depending on use.
