The AXIOM Beta Developer Kit is equipped either with a CMV12000 ZIF (Zero Insertion Force) socket or a THT (Through Hole Technology) socket image sensor board . This page tries show the differences between those two options and who might benefit from choosing one or the other.
The ZIF socket is useful for developers as it allows for frequent, easy sensor removal at the turn of a lever (zero force). The socket itself is reused server CPU socket (https://en.wikipedia.org/wiki/Socket_604) with a rather dense BGA (Ball Grid Array) which makes assembling this PCB a bit a bit tricky and testing/verification quite time consuming thus resulting in a slightly higher price. The ZIF socket does not allow attaching a heat sink to the back side of the image sensor in contrast to the THT option.
Who is it for?
Mostly developers and anyone who needs to swap image sensor often.
The THT socket is a custom manufactured CMV12000 2 part image sensor socket. Once the image sensor has been inserted into this socket it's almost impossible to take it out again without special tools - the danger of bending a pin of the image sensor or damaging the sensor itself is significant so we do not recommend attempting that. The THT socket provides space between the two pin banks of the image sensor and in the AXIOM Beta Compact Enclosure we utilize this space to attach a custom heat sink to the back of the image sensor. The Compact enclosure is only compatible with the THT socket Sensor Board.
Who is it for? It's the standard option, if you do not require to swap image sensor frequently this is the best option.
