RoHS Status

Engineered Components Company continues to use lead-tin solder in the standard construction of our products. We continue to receive an overwhelming majority of requests for our time tested, proven assembly methods using leaded solder and will continue to use those methods as our standard production. The lead is the only of the RoHS banned substances present in our standard products.

In an effort to satisfy the EU RoHS directive, Engineered Components Company will produce most products with "No Lead" or lead-free solder per request by customer. These products will be free of all 6 banned substances. The RoHS compliant products will be indicated by an "NL" suffix to the standard part number.

Some Engineered Components Company products (typically surface mount products) require the use of a high temperature internal solder that is greater than 85% lead by weight. These products are RoHS compliant by exemption 7a.

Soldering Recommendations

Engineered Components Company products are of hybrid construction utilizing active I.C.'s, P.C. boards, chip capacitors, resistors, wound inductors, and other components. Internal connections are all performed by hand soldering using SN63 eutectic solder with a melt temperature of 183 deg. C. The connections made to external leads are performed by hand soldering using SN10 solder with a melt temperature range of 268-299 deg. C All lead free products are soldered using Kestor's K100LD solder with a melt temperature of 227 deg. C.

Care must be taken by the end user to not expose our hybrid circuit products to temperatures that could remelt and possibly reflow the internal solder connections. We strongly recommend hand soldering all of our products using a lower melt temperature solder such as SN63. Our products with surface mount leads were designed to allow customers to use a non-feedthrough product where applications demanded it, but they should also be hand-soldered.
