Abstract
A printed circuit board test frame is characterized in that a substrate is connected with a cover plate; a liquid crystal display is connected with a conductive rubber strip and is fixed on the cover plate; a spring location bar, spring signal probes and a spring clamp lock are fixed on the substrate; and a base leg is fixed on the corners at the bottom of the substrate. When the printed circuit board test frame is installed in a printed circuit board, a chip and welding wires at the back of the printed circuit board do not touch human hands or other devices, operation is convenient, and fast and reliable test is achieved.
Description
Affiliated technical field
The utility model relates to a kind of printed circuit board test frame, and the printed circuit board (PCB) that is mainly used in liquid crystal display device module is behind the chip bonding wire, detect before the sealing protection.
Background technology
At present; printed circuit board (PCB) does not have stationary device in the detection behind the chip bonding wire, before the sealing protection; normally installation detects; promptly when having the sealing protection, chip just energising on the connecting terminal checkout equipment after the assembling fully of accessories such as backlight, chase, conductive adhesive tape, LCD is not detected; this installation detection mode speed is slow, and careless slightly meeting makes chip and bonding wire false touch cause chip to damage or the bonding wire broken string to staff or other device.
The utility model content
In order to solve present LCD in slow, the insecure problem of detection speed behind the chip bonding wire, before the sealing protection, the utility model provides a printed circuit board test frame, can neither damage bonding wire, again can the fast detecting printed circuit board (PCB).
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of printed circuit board test frame, it is characterized in that: substrate is connected with cover plate, LCDs is connected with conductive adhesive tape, and fix on the cover board, spring reference column, spring signal probe and Spring Card locking fix on the described substrate, its medi-spring signal probe penetrates substrate, and its end stretches out at described substrate another side, and the base leg is fixed on four angles of bottom of substrate.Described substrate and cover plate are connected through the hinge, and described cover plate can center on 180 ° of rotations of described substrate along hinge, when cover plate is closed, and spring kayser tightening cover plate.Described LCDs and described bus embed described cover plate and fixing, and described LCDs is electrically connected with described bus one end.
During testing printed circuit board; because there is the spring reference column at first can make the accurate contraposition of printed circuit board (PCB); the more important thing is and to withstand printed circuit board (PCB) to be measured; make the chip and the bonding wire at its back side unsettled; and can not touch other device and people's hand; therefore protection chip and bonding wire purpose have been reached; after cover plate is closed; spring kayser tightening cover plate; the conductive adhesive tape other end is electrically connected with electrode on the printed circuit board (PCB); the spring signal probe also with printed circuit board (PCB) on signal electrode contact conducting; the spring signal probe is terminal connects the test of can switching on of external host signal source, tests and unclamps the locking deck after finishing, and opens cover plate; just can take out printed circuit board (PCB), detection speed can reach 6 of per minutes.
The beneficial effects of the utility model are when detecting printed circuit board (PCB) behind the chip bonding wire, before the sealing protection, neither can damage bonding wire, can improve detection speed again.
