INVENTEC Solder Paste ECOREL™ FREE 305-31A
More than 2 decades of experience in high reliability markets such as automotive, energy and aerospace. For our
customers, having the correct choice of materials certainly contributes to increase in long term performance and to drop in
maintenance costs.
*
Key additional value:
The reliability of electrochemical corrosion (ECM) passes the "BONO test" (key technical parameter), which can monitor whether chemical residues remain inert after welding; The product is compatible with most three-proof paints on the market.
