Introducing LF-4300 (lead-free) and 4300 (tin-lead), two revolutionary synthetic solder pastes that offer such unparalleled versatility and forgiveness, we still don’t believe it.
Both the LF-4300 and the 4300 offer true multi-process capabilities, ideal for no-clean applications and also water washable, able to be cleaned using standard aqueous cleaning systems without saponification. Both formulas also utilize synthetic materials that deliver ideal printing characteristics, unparalleled lot-to-lot consistency and extremely long stencil life. LF-4300 and 4300 are also VOC and halide-free, and classified as RELO. When used as a no-clean, their flux residue remains clear and meets S.I.R. requirements as per IPC-TM-618.104.22.168. Unique features of LF-4300 and 4300 solder paste include:
- No-Clean and Water Washable (one product for both processes)
- LF-4300 complies with RoHS directive 2002/95/EC and is suitable for high temp. alloys up to 300ºC
- RELO flux classification
- No mid-chip beading
- Low voiding
- 12-hour stencil life
- 24-hour abandonment time
- Pin Probable for ICT inspection
- Compatible with AOI inspection
- Works well in convection and vapor phase processes
Both the LF-4300 and the 4300 feature 12-hour stencil life and 24-hour abandonment time so PC assemblers can change shifts or experience prolonged downtime without jeopardizing production yields. The LF-4300 also meets RoHS directive 2002/95/EC with lead content guaranteed at <200ppm.
