| AMTECH水溶性锡膏，LF4300，水溶性锡膏，水洗锡膏，水洗无铅锡膏，水溶性无铅锡膏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 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 . requirements as per IPC-TM-650.2.6.33. 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. |
