| Low Profile PGA Socket Carriers |
Mill-Max PGA socket carriers are a convenient way to load a PC board with "loose" receptacles in a PGA pattern. The PGA carrier is constructed of a molded polyester wafer fitted with tapered metal carrier pins. Loaded onto the carrier pins are groups of discrete receptacles. The internal spring contact of the receptacle provides self-retention to the carrier pin. During the soldering process, the carrier socket provides added weight necessary to keep the receptacles firmly in place as the circuit board passes over the solder wave. After soldering, the carrier is unplugged and may be recycled.
PGA socket carriers offer important user benefits. By eliminating the socket insulator, an extremely low profile is achieved, just .016" above the board. Lower profile reduces circuit inductance. Elimination of the socket body also provides improved ventilation as well as easier visual inspection of the solder joints.
Mill-Max PGA socket carriers are available in a variety of standard and custom configurations. Six different types of receptacles are now offered, including standard solder tail and low profile versions to fit .039" and .055" mounting holes.
Mill-Max receptacle shells are machined with a closed bottom to eliminate solder wicking and flux contamination of the contact area. All receptacles use beryllium copper "multi-finger" inner contacts, renowned for their reliability. Mill-Max socket carriers use tapered metal carrier pins, leaving no metal debris or adhesive residues on the rim or inner contact.
For large volume customers who want to achieve cost savings by having their carriers reloaded, Mill-Max offers a recycling program.
