Description

A kind of two-sided DIP Wave soldering fixture of double sided SMT surface mount elements

Technical field

The utility model relates to a kind of Wave soldering fixture, specifically a kind of two-sided DIP wave-soldering of double sided SMT surface mount elements Jig.

Background technique

Electronic circuit surface installation technique (Surface Mount Technology, SMT), referred to as surface mount or surface Mounting technique.It is it is a kind of will be without pin or short leg surface-assembled component (abbreviation SMC/SMD, Chinese claim sheet component) It is mounted on the surface of printed circuit board (Printed Circuit Board, PCB) or the surface of other substrates, passes through reflux The methods of weldering or immersed solder are subject to the circuit load technology of welding assembly.

The two-sided DIP Wave soldering fixture of surface mount elements used today has the disadvantages that

1, pervious two-sided DIP Wave soldering fixture design bracing wire both sides operation pcb board is opposite spelling, is existed when crossing wave crest Differential seat angle, subelement cross furnace will cause short circuit phenomenon 2, element crests be easy furnace after float high 3, pcb plate positioning operation time-consuming consumption Power.

Utility model content

The utility model is to solve traditional pervious two-sided DIP Wave soldering fixture design bracing wire both sides operation PCB Plate is opposite spelling, crosses after furnace will cause short circuit phenomenon, element crests are easy furnace and floats there are differential seat angle, subelement when crossing wave crest High, pcb plate positioning operation takes time and effort.The problem of.

The technical solution adopted in the utility model is: a kind of two-sided DIP Wave soldering fixture of double sided SMT surface mount elements, including Jig body drags tin piece, and the jig body is in rectangular configuration, it is characterised in that: offers in the jig body multiple Jigsaw, the left side of each jigsaw is equipped with push down element crests and prevent furnace after float high clinching and determine convenient for what pcb plate was sideling inserted into Position block.

For the quantity of the jigsaw to be a and arranged in arrays, the direction of all jigsaw is consistent.

Further, clinching includes cushion block and buckle；The upper surface of cushion block is arranged in buckle, is formed together L shape with cushion block Structure is fixed in jig body after passing through buckle and cushion block by screw.

Further, the locating piece is to be fixed in jig body the flexible sheet body with pedestal.

Further, the width for dragging tin piece is 3~5 millimeters.

The beneficial effects of the utility model and feature are: 1. eliminate original briquetting replaces reducing using two locating pieces Working hours are saved in two movements；2. increase L-type clinching, pushing down element crests prevents from floating height after furnace, reduces poor short circuit promotion directly Passband 3. drags tin piece width to be changed to the 3-5mm reduction bad 4. jigsaw mode of element short by the 1mm of script and is changed to unified direction, Facilitate personnel's operation, reduces poor short circuit after furnace.

Detailed description of the invention

Fig. 1 is the overall structure diagram of the utility model preferred embodiment；

Fig. 2 is the structural schematic diagram amplified at Fig. 1 dotted line；

Fig. 3 is the Section A-A structural schematic diagram of Fig. 2；

Fig. 4 is the schematic perspective view of vertical fiber orientation box；

Fig. 5 is the schematic perspective view of locating piece；

Figure label respectively indicates: 1-jig body, 2-jigsaw chambers, 3-clinchings, 31- cushion block, 32- buckle, 33- spiral shell Tin piece, 7-pedestals are dragged in silk, 4-locating pieces, 5-vertical fiber orientation boxes, 6-；

Specific embodiment

The utility model is further described with reference to the accompanying drawing:

Please refer to Fig. 1, a kind of two-sided DIP Wave soldering fixture of double sided SMT surface mount elements, including jig body 1, tin piece 6 is dragged, The jig body 1 is in rectangular configuration, it is characterised in that: multiple jigsaw 2, the jigsaw 2 are offered in the jig body Quantity be 4 and arranged in arrays, the direction of all jigsaw 2 is consistent, facilitates personnel's operation；

Referring to figure 2.~Fig. 3, the clinching 3 include cushion block 31 and buckle 32；The upper end of cushion block 31 is arranged in buckle 32 Face is formed together L-shaped structure with cushion block 31, is fixed in jig body 1 after passing through buckle 32 and cushion block 31 by screw 33, detains Plate 32 can effectively push down element crests and prevent from floating height after furnace, reduce poor short circuit promotion first-pass yield.

Referring to figure 4., multiple vertical fiber orientation boxes 5 are additionally provided in the jig body 1, by vertical fiber orientation box 5 optical fiber cables, which endways can be put, to be suspended in the air, and optical fiber cable can preferably be protected there is no heat transfer by not contacting with jig.

The left side of each jigsaw 2 is equipped with push down element crests and prevent furnace after float high clinching 3 and be sideling inserted into convenient for pcb plate Locating piece 4, the locating piece 4 is to be fixed in jig body 1 with the flexible of pedestal 7 (in Fig. 5 jig body 1 with) Sheet body；It only needs sideling to be inserted into when being packed into pcb board, i.e., in the gap between insertion jig body 1 and locating piece 4, is detailed in Fig. 5 (originally needs to rotate, dynamic two movements of clinching act, time-consuming, effort) using briquetting, can reduce poor short circuit after furnace.

The width for dragging tin piece 6 is 3~5 millimeters, compared to the prior art, drags tin piece width to increase, so that dragging tin The area that piece 6 contacts tin increases, and the enough gravitation of element number foot can be given to when crossing wave crest, reduces poor short circuit.
