Detection device
A detection device for a chip. A faulty chip is detected from a plurality of chips via the detection device. The chips are installed on a printed circuit board. The detection device electrically connected to the printed circuit board comprises a updateable chip and a substitute printed circuit board. The substitute printed circuit board is electrically connected to the updateable chip and comprises a plurality of pins disposed on two sides thereof for connecting to each chip.
1. A detection device, wherein the detection device detects a chip electrically connected to a printed circuit board, comprising:
an updateable chip, comprising a plurality of pins;
a substitute printed circuit board, electrically connected to the updateable chip, comprising a plurality of pins disposed on two sides of the substitute printed circuit board and electrically connected to the pins of the updateable chip; and
a switch connected to the chip and the updateable chip for controlling the chip and the updateable chip,
wherein when the chip is faulty, the updateable chip substitutes for the faulty chip.
2. The detection device as claimed in claim 1 , wherein the substitute printed circuit board comprises at least one fixing portion to fix the printed circuit board.
3. The detection device as claimed in claim 2 , wherein the substitute printed circuit board comprises three fixing portions.
4. The detection device as claimed in claim 1 , wherein the substitute printed circuit board comprises a shell for protecting the detection device.
5. The detection device as claimed in claim 4 , wherein the shell comprises a fixing element.
6. The detection device as claimed in claim 4 , wherein the shell comprises a space for containing the chip.
7. The detection device as claimed in claim 1 , wherein the pins of the substitute printed circuit board are pogo pin.
8. The detection device as claimed in claim 1 , wherein the pins of the substitute printed circuit board are flexible.
9. The detection device as claimed in claim 8 , wherein each flexible pin comprises a free end, the free end moves horizontally.
10. A detection device, wherein the detection device detects a plurality of chips electrically connected to a printed circuit board, comprising:
an updateable chip comprising a plurality of pins;
a connected printed circuit board, electrically connected to the updateable chip, comprising a plurality of pins;
a substitute printed circuit board, electrically connected to the updateable chip and the connected printed circuit board, comprising a plurality of pins disposed on two sides of the substitute printed circuit board and electrically connected to the pins of the updateable chip; and
a switch connected to the chip and the updateable chip for controlling the chip and the updateable chip,
wherein when the chip is faulty, the updateable chip substitutes for the faulty chip.
11. The detection device as claimed in claim 10 , wherein the substitute printed circuit board comprises at least one fixing portion to fix the printed circuit board.
12. The detection device as claimed in claim 11 , wherein the substitute printed circuit board comprises three fixing portions.
13. The detection device as claimed in claim 10 , wherein the substitute printed circuit board comprises a shell for protecting the detection device.
14. The detection device as claimed in claim 13 , wherein the shell comprises a fixing element.
15. The detection device as claimed in claim 13 , wherein the shell comprises a space for containing the chip.
16. The detection device as claimed in claim 10 , wherein the pins of the substitute printed circuit board are pogo pin.
17. The detection device as claimed in claim 10 , wherein the pins of the substitute printed circuit board are flexible.
18. The detection device as claimed in claim 17 , wherein each flexible pin comprises a free end, the free end moves horizontally.
