Thru Hole (TH) Adaptor
If the target circuit board exists with a thru-hole
pattern, then a TH adaptor can be used with a
GHz socket. TH adapter (See figure 13) has
terminal pins on the bottom side and round pads
on the topside. It is slightly larger than the IC
size. It has threaded insert on four corners. GHz
socket can be mounted on to this adapter using
the screws that mate into the threaded insert.
Materials
Non-clad FR4, Phosphorous Bronze pins,
threaded insert. The solder balls from IC
package come in contact with the top end of
elastomer wire.
The bottom end of elastomer wire contacts the
TH adaptor board pad. The bottom side of the
pad is connected to the target circuit board via
terminal pins and thereby makes an electrical
path for the signal. Figure 14 illustrates this
concept graphically.
TH adaptor can be plugged onto a socket
receptacle which is surface mount soldered on to
the target PCB. Figure 15 illustrates this concept
graphically.
