Solder pastes FELDER
No-clean SMD soft solder pastes
Homogeneous, ready-made and low-odor mixture of metal powder, binders, solvents, fluxes and thixotropics. | |
ISO-Cream® "EL 5510" | No-clean SMD solder paste, best wetting in lead-free applications. Premium contour stability, optimal printability, very high surface resistance. Long processing period of at least 48 hours. Suitable for all reflow applications. (ROL0) |
ISO-Cream® "Clear" | No-clean SMD solder paste, best wedding on all PCB surfaces especially NiAu and NiPd unter normal conditions. Ptotective atmosphere also in the vapor phase, halogene-fre (<0.01%), rosin-free, clear and unobtrusive residues, low tendency to void generation |
ISO-Cream® "EL 3202" | No-clean SMD solder paste, best suitability for vapor phase soldering. Particularly suited for the stencil printing. Low water-clear residues. Long processing period of at least 48 hours. (ROL1) |
ISO-Cream® "EL 3203" | No-clean SMD solder paste with excellent wet bonding strength for automatic placement machines with high acceleration or deceleration. Printed circuit boards up to 32 h can be equipped. High contour stability, high service life on the stencil (up to 8 hours). (ROL1) |
SMD special soft soldering pastes
For soldering of poorly solderable components with downstream cleaning process. Homogeneous, ready to use and low-odor mixture of metal powder, binders, solvents, fluxes and thixotropics. | |
ISO-Cream® "RA 2601" | Flux according to DIN EN 29454.1, 1.1.3.C or DIN EN 61190-1-3, ROM1. Especially for poorly wettable solder partner. The flux residues on the soldered circuits should be removed. |
ISO-Cream® "ELW 2303" | Flux according to DIN EN 29454.1, 1.1.3.C or DIN EN 61190-1-3, ORM0. Solder paste with water soluble residues. Excellent wetting on all common surfaces. The residues can be completely removed with distilled water. |
