Relays won't melt during reflow soldering

The Excel Cell Electric GQ Series of 1-Pole Reflow Solderable Relays, are now available with THR (Through-Hole Reflow) Technology from New Yorker Electronics. The THR Series Through-Hole Type Electromechanical Relays from Excel Cell Electronic (Goodsky/ECE) now allow the GQ Series to withstand the harsh melting temperatures of the reflow soldering process.

In the past, the primary issue preventing through-hole components from passing through the reflow soldering process is that the process requires such high temperatures.

This melts the solder paste in a matter of minutes and the plastic material in the through-hole relay could also melt and cause an electrical malfunction.

However, after years of research in through-hole type electromechanical relays, Goodsky/ECE discovered several supreme standard plastic materials that can withstand the high, punishing temperatures of the reflow soldering process.

From this, ECE developed the THR Series of Relays. The THR version can withstand the IEC 60068-2-58 Reflow Soldering.

To help determine individual cost savings, simply submit through-hole reflow soldering profiles with the preferred cross relays to New Yorker Electronics for an analysis.

Excel Cell Electronic’s GQ Series is not the only series that can be specially made into THR standard. Other major relay series such as RWH, JE, GCJ, GU, EMI-2P, SF and others can be customised to THR versions.

Additional values and features can be added such as UL Class F, IEC 60335-1 glow wire and halogen free.
