AE 606 Oxley SMOX PCB test points from Aerco

Low contact resistance test terminals have been designed to provide simple testing of PCB circuits in manufacturing production lines.

The Oxley SMOX Series of surface mount test terminals for PCB assembly line testing is now available from Aerco.  The SMOX Series has a unique retention mechanism which enhances reliability through low stress contact.

Two different versions are available – HT Type SMOX for use with RoHS compliant high temperature lead-free solders and Standard Type SMOX for use with low temperature tin solders. The SMOX Series is compatible with pick and place machines for automated manufacturing processes and also available loose for hand assembly.

Featuring a specially designed socket, the SMOX Series is the only surface mount ball and socket test point currently available on the market offering easy low contact resistance and gentle detachment.  The single pole devices require a tiny minimum pad size of only 2mm, so are suitable for testing even very tightly congested PBC designs.  Highly resilient, they can be used over a temperature range of -55C to +125C. The test point and socket body is manufactured from copper alloy with a gold-plated test point finish as standard, optional Palladium, silver, nickel, tin lead finishes are also available.

Other technical specifications include maximum contact resistance of 2mΩ, socket insulation resistance of 10,000MΩ.  Typical retention force is 0.2Kg (angles < 60 degrees or ± 30 degrees) off perpendicular and typical retention torque of 200gcm (angles > 30 degrees or perpendicular). Solderability exceeds the requirements of BS2011 (IEC 68) Test T and meets MIL-STD-202 Method 208.
