Abstract
The invention discloses a testing jig of a circuit board. The testing jig comprises a rectangular cabinet for placing a PCB (printed circuit board), an overhead board, a connecting column and a pressure rod, wherein the overhead board is vertically arranged above the cabinet, the connecting column and the pressure rod are connected with the overhead board, and an air blowing device for blowing air to the PCB is arranged in the cabinet. According to the MDA (manufacture default analysis) testing jig of the circuit board disclosed by the invention, the residual solder splash on the PCB is blown into a solder splash box by the air blowing device and is collected by the solder splash box, the short circuit of a probe in a test is avoided, the testing accuracy and the testing effect are improved, the workload of the manual solder splash removing is reduced greatly, and the testing efficiency is improved.
Description
Technical field
The present invention relates to a kind of circuit board and measure tool, relate in particular to a kind of MDA measurement jig.
Background technology
MDA (Manufacture Default Analysis) measurement jig is a kind of circuit board testing jig; It is the carrier of pcb board production test; The on-line testing machine can be tested various types of pcb boards by means of the MDA measurement jig effectively, reaches the purpose of control pcb board quality.The MDA measurement jig has many residual scruffs in when test on the pcb board, be short-circuited, disturbed test process, influenced test accuracy and tested effect, reduced testing efficiency owing to after the frequent test scruff is dropped to make probe very easily touch scruff; The artificial scruff of removing of needs has been wasted man-hour when short circuit occurring on the other hand.
Summary of the invention
Technical matters to be solved by this invention provides a kind of circuit board testing jig, and probe is short-circuited when avoiding testing, and improves test effect and testing efficiency.
For solving the problems of the technologies described above; The present invention provides a kind of circuit board testing jig; Comprise one place pcb board the rectangle board, be vertically installed in the sky plate of board top, joint pin and the pressure bar that is connected with said sky plate; It is characterized in that, be provided with the blowning installation of blowing in the said board towards pcb board.
One side edge of said board is provided with a groove, is used to collect by blowning installation blow into next scruff.
The side at said board edge be provided with one stop gas that said blowning installation blows out or scruff dregs diffusion retaining wall.
The edge of other of said board three sides be respectively arranged with one stop gas that said blowning installation blows out or scruff diffusion retaining wall.
On the said board in the outside of said groove, also be provided with a retaining wall.
The beneficial effect that the present invention reached:
Circuit board MDA measurement jig of the present invention; By blowning installation scruff residual on the pcb board is blown in the scruff box and to collect, probe is short-circuited when avoiding testing, and has improved test accuracy and test effect; Significantly reduce the work of artificial clear scruff, improved testing efficiency.
Description of drawings
Fig. 1 is a measurement jig synoptic diagram of the present invention;
Fig. 2 is the side view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the present invention is further described.Following examples only are used for technical scheme of the present invention more clearly is described, and can not limit protection scope of the present invention with this.
Like Fig. 1, shown in Figure 2; Circuit board MDA measurement jig of the present invention comprises a board 4, is vertically installed in the sky plate 1 of board top, is connected with joint pin 2, pressure bar 3 on day plate 1; Connect a needle plate 6 through spring 5 on the board 4; To the hole, front bevel angle, needle plate 6 top panels are support plate two 45 ° of needle plate 6 fore devices, and support plate is the board under test rest area.Board under test through on the contact of the probe on the needle plate 6 support plate is tested; Can produce scruff after the frequent test, the scruff that drops makes short circuit easily between the probe, is provided with retaining wall 7 around board 4 tops; To constitute the space of relative closure; The gas that blowning installation 9 is blown out blows the scruff on the pcb board off, and blows to scruff collection box 8, and scruff is blown into unified collection the in scruff collection box 8 backs and clears up.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from know-why of the present invention; Can also make some improvement and distortion, these improvement and distortion also should be regarded as protection scope of the present invention.
