General Description:
PCB Pin Sockets for Model 990Enh-Ticha/995FET-Ticha Discrete
Operational Amplifier

It is highly recommended that the user not solder the pins directly to the mating printed circuit board. Overheating the pin during soldering creates a cold solder joint at the other end internal to the module and can lead to failure. Permanant soldering of the pin prevents easy removal of the module. Lastly, soldering prevents one from servicing components which may lie underneath the module.

Many types of sockets for 0.040” diameter pins are available from several manufacturers. Sonic Imagery Labs uses and stocks the sockets from Mill-Max. Sockets from other manufacturers listed below perform equally well. These sockets can be soldered or swaged in your printed circuit board. Additionally, users can purchase a set of six from Sonic Imagery Labs online.

The sockets can be mounted in from the top side of the PCB or from the bottom side. If top side mounting is used, the passive components for the 990Enh-Ticha could ideally laid out underneath the op-amp. This would minimize long traces and associated parasitics with a PCB layout having components on the outer perimeter of the opamp.
