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 lead-free solders (high temperature) and Standard Type SMOX for use with tin solders (lower temperature). 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 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 -55degC to +125degC. 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 2mOhm, socket insulation resistance of 10,000MOhm. 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.
