Description
Technical field
The present invention relates to circuit module measuring technology, more particularly to a kind of four side stamp hole package module test fixtures and make
Use method.
Technical background
Stamp hole, also known as half bore pad are originally that the jigsaw mode used when plate is done in a kind of printed board, afterwards because of its processing side
Just, of low cost, be suitable for attachment welding, often adopted as signal input and output by the circuit module of some function opposite independents
With, thus become a kind of new packing forms, i.e., " stamp hole encapsulation ".Stamp hole package module is generally " both sides " or " four
Side " signal draws pattern, such as WiFi module, USB module, 9G45 modules.But these modules are when producing detection, due to not having
It can not be clamped in signal leading-out connector, common test fixture, also just cannot achieve dependence test, sealed to the type
Die-filling piece of detection brings puzzlement.Existing method is to be welded test board and tested module pin with conducting wire, with this
Signal is drawn or inputted tested module, realizes the detection to module.Conducting wire is removed from tested module again after being completed.
Although this method solves the test problem of module, but there are many drawbacks.Such as：For pin number more and spacing compared with
For small module, pin leads welding difficulty can then increase with increasing for number of conductors, and welding process is caused to be taken a lot of work expense
When；For the underproof module of one-time detection, then need that sealing-off pin pad conducting wire is repeated several times, to repair re-test, because
This is easy to cause the damage of module pin pad, and module is caused to scrap；For the qualified module of detection, it is also necessary to pin pad into
Row removes the process of extra scolding tin, with the quality requirement etc. for meeting module appearance and when pin pad welds again.On
The factor of stating causes the entire production process inefficiency of module, cost to occupy high, product quality and cannot be effectively ensured, when production batch
It is particularly problematic when larger.
Invention content
Technical problem to be solved by the invention is to provide a kind of folders that can be tested four side stamp hole package modules

It wants, top outer is designed with convex block 401, is higher than 2 millimeters of top surface, is 7 needle body of testing needle and extraction line reserved space and channel；
4 bottom centre of movable block is slightly designed with guide pin 402,402 design diameter of guide pin by front end（φ8mm）, length（10mm）, can be fully
It is inserted into the pilot hole 203 of turntable 2.Position design is reduced between a part and main 3 among 4 bottom of movable block as needed
It is smooth to ensure that movable block 4 moves to reduce friction for contact surface；4 Front-end Design of movable block has mounting hole 403, mounting hole 403
Set with dress 8 mounting hole of needle plate it is corresponding, ensure dress 8 bottom of needle plate and left and right face face corresponding with movable block 4 it is concordant.
Main 3 sizes（160mm×160mm）, central design has opening 302（46mm×46mm）, size meets saddle 5 and puts
Set needs；Main 3 bottoms are designed with cavity 301, cavity inner edge size（144mm×144mm）, depth design 8mm and turntable 2 are thick
It is consistent to spend size.Cavity frame bottom is designed with threaded hole（M3×6mm）, for being installed with pedestal 1；Main 3 bottoms are leaned on
Two faces of 2 cursor of nearly turntable, 201 one end are respectively designed with limit adjusting screw hole 308, by installing and adjusting the first limit
Screw 310 and the second stop screw 311（M2.5×12mm）, limitation turntable 2, which is crossed, to be turned, and is reached prevention and was exerted oneself because stirring screw rod 10
Purpose that is violent and damaging fixture.
Main 3 top is vertically, there are four guide grooves 303 for the design of left and right central axis, is used for installation activity block 4, guide groove 303
Inside dimension（Long 41mm × wide 38mm × depth 10mm）Design matches with 4 appearance and size of movable block, and it is logical that bottom is designed with kidney-shaped
Hole 304 passes through for 4 guide pin 402 of movable block；303 top design of guide groove has a mounting groove 305 of cover board 6, install after cover board 6 with
Guide groove 303 forms cavity, forces the movable block 4 in guide groove 303 that can only be moved in guide groove 303；Guide groove 303 is by main 3 outside
Acies is designed with block 307, and 307 top bottom of block facilitates 7 line of testing needle to draw in 303 top 2mm of guide groove；Main 3 top
It is designed with kidney slot 306 close to one end of 2 cursor 201 of turntable, positions and dimensions meet need when screw rod 10 stirs turntable 2
It wants.
2 diameter dimension of turntable（φ120mm）, thickness（8mm）, centre is designed with the first centre bore 202（φ
40mm）；Between 2 edge of first centre bore 202 and turntable four pilot holes 203 are designed along vertically and horizontally central axis；It is oriented to
When the center location of circular arc is detached from tested module 01 by testing needle 7 on 203 central axis of hole, 01 central point of tested module to guide pin
The spacing in 402 centers of circle determines；If using 2 center of turntable as the center of circle, when clamping tested module 01 with testing needle 7, in tested module 01
The spacing in heart point to 402 center of circle of guide pin is that be formed by intermediate circular arc line be δ to radius, with circular arc on 203 central axis of pilot hole
The center of circle be starting point, draw tangent line L toward left-hand δ from right, then the intersection point of this tangent line and δ are the circle of 203 other end circular arc of pilot hole
Heart position；203 circular arc of pilot hole and width dimensions and 4 guide pin of movable block, 402 diameter（φ8mm）Design matching, ensures 2 turns of turntable
Pilot hole 203 can drive 4 smooth movement of movable block by guide pin 402 when dynamic, and 7 clamp or release of testing needle can finally be made to be tested mould
Block 01.
Outer edge between two pilot holes 203 for selecting turntable 2 adjacent designs cursor 201, in 201 end of cursor
Design runs through threaded hole（φ6mm）, threaded hole and installation screw rod 10 are mating, drive turntable 2 to rotate by stirring screw rod 10, and can
Prevent turntable 2 from malfunctioning to tighten screw rod 10 as needed.
