APPLICATION LEAD-FREE SOLDER BAR LF-307

– Solder bar LF-307 has been proven to perform well in automatic wave soldering, selective soldering, and static soldering.

– In the LF-307 solder bar, copper tends to dissolve into the solder from the circuit boards and component leads. If the copper content in the solder bath exceeds 0.85%, it is likely to cause an increase in the rate of bridges, tapes, and other defects.

– To maintain the copper level within the permissible limits in the solder bath, Electroloy recommends the use of a coating alloy on LF-314B. The LF-314B has a lower copper content than the LF-307 to ensure that the copper content in the solder pot is always below the critical level of 0.85%.

– Copper content verification is easy with lead-free Solder Pot Analysis provided by Electroloy.

– Statistical analysis of your LF-307 soldering pot will help you monitor copper levels over time and give Make key decisions to achieve good manufacturing productivity with our LF-307 solder bar.
