ERNIPRESS Trapezoidal-Connectors Series TMC D-Sub Subminiatur-D Connectors to DIN 41 652/IEC 807-3 with Press-fit zone General Benefits of ERNIPRESS Solderless press-in technology for connectors in bus systems permits rationalized and reliable connecting of connector and printed circuit board. • Gas-tight, corrosion proof and strong mechanical connection • No soldering errors • No thermal stress • Easy handling • No flux problems • Low tooling investment • Contact is made in the copper-layer, not in the tin-layer of the pcb • Assembly possible on both sides • No additional washing, therefore no environmental pollution due to clearing agents TMC series connectors are frequently used for interface connections. To provide a rationalized connecting technique in these applications, too, ERNI also offers the ERNIPRESS termination method (solderless press-in technology) for these connectors. The socket (S) and plug (P) connectors have the wellproven elastic press-in zone (EE). The contacts of the ERNIPRESS plug connectors (P) are made from a solid round wire. Accessories For series TMC connectors ERNI has a wide range of accessories available. No matter whether the important criterion is easy assembly, different types of mounting, electromagnetic compability, locking devices or connector housings, you will find attractive solutions at ERNI.

In many cases our customers take advantage or our full service right from the start: that is to say, we have the printed boards produced to the customer’s specification, take over the testing of the printed board prior to component-mounting, carry out all necessary component-mounting, and electrically test the printed board systems after assembly. Thus the customer receives backplane circuitry ready for installation, with the ERNI manufacturer’s and test certificate. This method does not have to be of benefit merely for largescale series production. No indeed, in many applications ERNI offers decisive technical advantages even at low unit volumes. We only need mention here the key phrases high polarity, double-side mounting, multilayer printed boards and adapter slots. Together with our customers, we devise and develop the benefits which ERNIPRESS can offer for the application. So let’s talk about your applications. Together we should work out the benefits which ERNIPRESS offers you.

On the plug-in side, the widely-used hexagon interlock bolts with inside thread can be seen. The spacer bolts with inside thread for fixing on the printed board are likewise riveted on at the factory. All accessory parts are available with thread versions M3 or 4/40 UNC. The types of thread may also differ within a connector, e.g. M3 for fixing to the printed board and 4/40 as an inside thread for interlocking. 26 Catalog E 074484 04/04 Edition 6 www.erni.com PCB requirements pcb, a selective rack technique, flexible anode arrangement and continuous plating bath monitoring are suggested. c.) Drillhole diameter and positioning. Maintaining the correct roughness of the drillhole wall and restricting drill bit travel are critical production processes. d.) PCB hole and layout requirements. A minimal residual ring width of 0.1 mm, finished hole tolerances, layer thicknesses and a high quality consistent conductive pattern are all critical. e.) Insertion and retention forces. Measurement of these forces should be checked. Insertion and retention forces The design of the press-fit zone of the ERNIPRESS connectors performs a dual function. On the one hand this design has high elasticity and therefore can accomodate large hole tolerances. On the other hand, the press-fit zone’s design ensures high edge loadinge at the copper layer of the PCB hole resulting in a gas-tight, corrosion-proof and mechanically secure connection. Due to the special shape of the press-fit zone, insertion forces are not detrimental to the hole plating. Retention forces of the contacts in the PCB hole are sufficient to withstand the torques which occur during wire wrap termination. Typical average values for retention force are between 40 – 70 N per contact depending upon PCB thickness.

The dimensions of the plated through drillholes and their hole design are described in DIN 41 611 as well as DIN IEC 60 352-5. The quality and long-term performance of a press-fit connector are influenced by the following factors: a.) Base material of the PCB. To meet UL requirements, epoxy glass fabric type Hgw 2372.1 to DIN 7735, FR 4, should be used. b.) Adherence to drillhole tolerances. For optimum and uniform plating of the metallization of the
