Abstract
The utility model provides a kind of daughter board connector processing jig, its structure comprises plate body, is arranged on the left ear of the plate body left and right sides and auris dextra portion, described left ear, auris dextra portion respectively arrange a cylindrical stud, and two studs are all arranged on the same side in left ear, auris dextra portion.This kind of daughter board connector processing jig compared to the prior art, have reasonable in design, structure is simple, the feature such as easy to use, only this tool two reference column need be aimed at two pilot holes of PCB, directly connector is placed on PCB after print solder paste along tool limit and welds PAD, cross twice reflow soldering, thus reduce welding cost, improve welding quality, ensure the reliability of SMT welding, product percent of pass is high.
Description
Technical field
The utility model relates to field of computer technology, specifically simple, the daughter board connector processing jig of a kind of structure.
Background technology
Existing server daughter board connector needs to be plugged on and board does SMT welding, and the pin pin of welding is intensive and quantity is more, and when placing this connector after the tin cream of printing two sides, pin pin easily misplaces crooked.
In actual process, connector is all manual placement, owing to not having calibration point, will occur crooked like this, will have a strong impact on the welding quality of daughter board connector like this, cause defective goods, substandard products in the majority, cause the increase of production cost when SMT welds.For avoiding this problem, BOT face reflow soldering---reflow soldering of TOP face---connector reflow soldering is adopted to amount to 3 times reflow solderings, avoiding directly connector being placed on welding on tin cream causes crooked, but this kind of mode both increased cost, and cross the quality that three times reflow solderings also can affect components and parts.
Based on this, now provide a kind of daughter board connector processing jig of with low cost, accurate positioning.
Summary of the invention
Technical assignment of the present utility model solves the deficiencies in the prior art, provides the daughter board connector processing jig that a kind of structure is simple, result of use is desirable.
The technical solution of the utility model realizes in the following manner, a kind of daughter board connector processing jig, its structure comprises plate body, is arranged on the left ear of the plate body left and right sides and auris dextra portion, described left ear, auris dextra portion respectively arrange a cylindrical stud, and two studs are all arranged on the same side in left ear, auris dextra portion.
When reality uses, the stud socket in left ear, auris dextra portion, in the perforate that daughter board connector is offered, realizes the precise positioning of the pcb board to daughter board connector, thus SMT welding can be carried out smoothly.
As preferably, described left ear, plate body, auris dextra portion coordinate formation one oblong openings, and this opening is that golden finger exposes mouth.This golden finger exposes the setting of mouth, and the golden finger of daughter board connector pcb board can be facilitated to weld in time, thus removes the complexity of multi-reflow welding from.
As preferably, described plate body is provided with calibration post, this calibration post is arranged on the plate body back side.This calibration post can coordinate the action of stud integral calibration further, makes welding process more accurate.
Further, described calibration post is stepped, and namely the outermost end diameter of section of this calibration post is less than inner diameter of section, and the outermost end of this calibration post is curved.The calibration post of this structure can the carrying of convenient staff, and practical.
In sum, the beneficial effect that the utility model is compared with prior art produced is:
A kind of daughter board connector processing jig of the present utility model has the features such as structure is simple, easy to use, novel, only this tool two reference column need be aimed at two pilot holes of PCB, directly connector is placed on PCB after print solder paste along tool limit and welds PAD, cross twice reflow soldering, thus reduction welding cost, improve welding quality, ensure the reliability of SMT welding, product percent of pass is high.
Accompanying drawing explanation
Accompanying drawing 1 is Facad structure schematic diagram of the present utility model.
Accompanying drawing 2 is structure schematic diagram of the present utility model.
Accompanying drawing 3 is overlooking surface structural representations of the present utility model.
Mark in accompanying drawing represents respectively:
1, left ear, 2, plate body, 3, stud, 4, auris dextra portion, 5, calibration post.
Embodiment
Below in conjunction with accompanying drawing, a kind of daughter board connector processing jig of the present utility model is described in detail below.
As shown in accompanying drawing 1, Fig. 2, Fig. 3, this a kind of daughter board connector processing jig, its structure comprises plate body 2, is arranged on left ear 1 and the auris dextra portion 4 of plate body 2 left and right sides, described left ear 1, auris dextra portion 4 respectively arrange the same side that cylindrical stud 3, two stud 3 is all arranged on left ear 1, auris dextra portion 4.
Described left ear 1, plate body 2, auris dextra portion 4 coordinate formation one oblong openings, and this opening is that golden finger exposes mouth.
Described plate body 2 is provided with calibration post 5, this calibration post 5 is arranged on plate body 2 back side.
Described calibration post 5 is stepped, and namely the outermost end diameter of section of this calibration post 5 is less than inner diameter of section, and the outermost end of this calibration post 5 is curved.
Above embodiment is only for illustration of the utility model, and be not limitation of the utility model, the those of ordinary skill of relevant technical field, without departing from the spirit and scope of the present invention, can also make a variety of changes and modification, therefore all equivalent technical schemes also belong to category of the present utility model.
