SMD soft solder paste ISO-Cream "EL 3203"
The solder paste ISO-Cream® "EL 3203" - LEAD-FREE is a homogenous, ready-to-use and odourless mixture made of metal powder, bonding agents, solvents, fluxes and thixotropic agents.This paste has excellent wetting qualities and is excellently suited for soldering of difficult surfaces. The flux residues show a very high surface resistance. The solder paste FELDER ISO-Cream® "EL 3203" is insensitive to humidity and temperature. It shows no tendency to solder-ball formation on chip-resistors and capacitors.
FELDER ISO-Cream® "EL 3203" has a very strong wet bonding force and is also suitable for machines with very high accelerations/decelerations. It has a very long stencil time and can be used in printing machines with a temperature control unit (very strong ventilation). The rheology of this paste has been optimised in order to achieve excellent printing qualities on narrow openings as well as a good first print after longer breaks. Laboratory tests have shown that the first print after a break of 8 hours was flawless. FELDER ISO-Cream® "EL 3203" distinguishes itself in long adhesiveness. Printed circuit boards can be assembled even 32 hours after the printing (depending on the room temperature and humidity).
