Aries Electronics, an international manufacturer of standard, programmed and custom interconnection products, has announced that its entire line of universal zero insertion force (ZIF) test sockets are now RoHS compliant. The company offers four types of ZIF test sockets: DIP ZIF, PGA ZIF, PLCC ZIF and SOIC ZIF. These universal ZIF sockets accept all package sizes regardless of the row-to-row dimensions and pin counts of any individual package. And, because no force is required to insert or remove a component from the socket, the legs remain straight and undamaged after insertion. The sockets' contacts are normally closed to eliminate dependence on plastic, which helps to sustain contact.
For the DIP ZIF sockets, the socket handle can be configured with closed contacts when in the up or down position and can be mounted on the right or left side. Boasting a life cycle of 25 000 to 50 000 cycles, these are available in pin counts of 24, 28, 32, 36, 40, 42, 44 and 48.
The contacts on PGA ZIF test sockets are activated by a strong metal cam, and the handle can be placed on the left or right side. These sockets are available in a grid size of 13 x 13, 15 x 15, 17 x 17, 19 x 19 or 21 x 21, plug into standard PGA sockets and have a contact current rating of 1 A.
The PLCC ZIF test sockets are sold with 'insert plates' that allow the socket to accept PLCC pin counts of 20, 28, 32, 44, 52, 68 and 84. PLCC devices are inserted in the socket 'live bug' style (pins down). The socket contains a bed of contact pins that are terminated in solder tail pins that mount to the customer's PCB. This socket has a life cycle of 10 000 insertions.
The SOIC ZIF test socket accepts all gull-wing and J-lead SOIC devices up to 44 pins, has an optional device lifter for easy package removal, and has an operating temperature of 125°C.
Aries will continue to offer the standard non-RoHS compliant version of these sockets for customers who require tin/lead plating. All of their test sockets are available in custom materials, platings, sizes and configurations to suit specific customer applications.
