• SMT (pin type -30) uses a standard reflow process to mount the sockets to the target PCB. These sockets mount in the same footprint as the IC, but typically require a mimimum clearance of 6mm betyond the package's periphery. In situations where adjacent components lie in this area, either the socket body can be modified to clear the components, or a special raised SMT (pin types -28 or -29) pin can be used in place of the standard SMT pin. These pins raise the socket body from 2-5mm above the PCB. Although this method does not require any drilled holes in the target PCB, it is highly recommended to provide two such plated holes in order to accomodate mounting pegs and greatly strengthen the physical connection between the socket and PCB. Alternatively, epoxy can be used to strengthen the connection, but this more or less creates a permanent bond between the socket and PCB.
• Through-hole (pin type -70) requires plated holes to be drilled in the PCB into which the pins of the socket will be soldered. This provides for a very robust and reliable electrical and mechancial connection. However, the electrical performance is reduced due to the longer pin lengths. This method is highly suitable for burn-in applications.
• Compression (pin type -90) mount removes the need for any soldering and just requires the socket to be held to the PCB via screws. The benefit of this method is that it allows the customer to easily attach the socket to the target board in the lab, without the extra cost, lead-time, and potential problems caused by sending the board to an assembly house. However, this method requires that the target PCB has mounting holes drilled to accomodate the mounting screws and socket body alignment posts. Furthermore, depending on the size of the IC, the PCB thickness, etc., a backing plate is required to provide rigidity and ensure the socket pins contact the PCB pads. This plate can usually be modified to accomodate any backside compononents.
