Erni has announced it is now offering DIN connectors with THR (through hole reflow) termination in tape-and-reel packaging for fully automatic assembly. This enables economic and automatic processing for these somewhat larger components as well, it says. The first standard connectors according to DIN 41612/IEC 60603-2 with THR termination in tape-and-reel packaging are already being used in large volumes by an Erni customer from the telecommunications sector.
Upon request, ERNI supplies its customers with DIN-variants with a black housing and a pick-and-place pad in the tape-and-reel packaging. This permits fully automatic processing with SMT placement machines. In this way, the boards can be soldered in a single operation, thus eliminating the potential need for hand soldering or selective soldering. This, in turn, boosts quality and reduces the amount of floor space and operational resources needed for production.
The product variants used here employ insulation housings made of heat-resistant thermoplastic. Consequently, the connectors can be soldered using wave or reflow soldering without lead and in conformance with the EU's RoHS directive. For the THR version, the following types are available: C, C/2, C/3, CD, R, R/2, R/3 and RD.
Using THR-SMT termination makes it possible to take advantage of fully automatic SMT processing with little or no change to the layout. For this reason, the company has already expanded different connector series to include versions with THR termination.
ERNI offers a wide range of connectors according to DIN 41612/ IEC 60603-2, from 2- and 3-row standard types up to 4- and 5-row high-density versions (up to 160 pins), as well as DIN connectors for the power supply. There are variants available with different termination types (such as the press-fit, dip-soldering, wire-wrap, and crimp techniques) as well as THR.
