We are the APEX EXPO and we got to meet with our favorite solder paste maker AMTECH, maker of the AMTECH LF-4300 solder paste!
AMTECH is a leading developer, manufacturer and supplier of specialty products and materials for the electronics assembly marketplace. Our RoHS-compliant products include solder pastes (lead-based and lead-free), tacky and liquid fluxes, solder powder, core wire and bar solder and process support products.
AMTECH offers highly individualized solutions to customers large and small, from expert product recommendations and product technical data, to intelligent answers to complex manufacturing process problems: cost-saving answers that can enhance your productivity and profitability by keeping your SMT process lines up and running.
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-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.
