EMMC first identifies foot 1, and EMMC first identifies that foot 1 can correctly judge placement position.The display screen and touch screen for connecting mainboard can
For tester's operation easy to use.Volume add-substract key and reset can meet tester's button operation demand.SD storage cards, USB
Interface and earphone interface meet tester's use demand.Test machine is integrally easy to assemble, can dismount integrated testability frame easily in this way
So as to the problem in inspection test procedure.It in the present embodiment, is tested by taking EMMC as an example, the utility model testing jig can also be surveyed
Try other chips such as MCU.
Products characteristics：
1. support is hot-swappable, card reader and computer connecting test can be directly inserted.
2. the consistent IC chip of various encapsulation compatible simultaneously.
3. compatible different size IC (11.5mmx13mm simultaneously；12mmx16mm；12mmx18mm；
It 14mmx18mm), can self-changeable limitting casing realization versatility reduction use cost.
4. easy to maintain, bad probe is replaceable, and recycling rate of waterused is higher, reduces use cost.
5. compatibility has ball to be tested without ball, versatility is good, reduces use cost.
6. Manual turnover cover formula structure is used, it is easy to operate simple.
7. using kickboard structure, registration picks and places IC conveniently, working efficiency higher.
8. it can be tested and low-level formatting.
9. PCBA board can be replaced according to specification, operated with, realize one module multiple usages.
Testing jig is introduced using detailed step：
1. the selection limitting casing identical with IC sizes is by direction in kickboard.
