Description
Technical field
The utility model relates to the processing of electronic devices and components, be specially a kind of go between for half hidden SOP remove gold, ward off tin frock.
Background technology
Remove gold, ward off tin and mainly remove Gold plated Layer, oxide layer, contamination etc. on electronic component down-lead, object avoids the generation of " gold is crisp ", improve the reliability after components and parts welding equipment, this technology is widely used in highly reliable requirement as in the assembling of aerospace level electronic product.Current electronic devices and components are just towards 3-D stacks encapsulation future development, for adapt to High Density Packaging, the 3-D stacks sealed storage device being representative with 3DPlus company oneself be applied in more and more widely in space product printed board (PCB) electronic assembly part.But because the technique of this kind of 3-D stacks packaging, structure cause its pin portions to be hidden in bottom device body, cause it to remove gold, to ward off tin operation very difficult, slightly do not note to be stained with solder to device body, cause device to be scrapped.Existing technology adopts a kind of peelable protecting glue to protect device body, and then operating personnel carry out warding off tin warding off Xi Guozhong with hand-held tweezers gripping element.There is following problem in this kind of process:
1. smear need be very careful for peelable welding resistance glue, and careless slightly contamination can cause gold on device wire, it is thorough to ward off tin, affects soldering reliability.
2. the peelable welding resistance adhesive curing time is long, needs 4 ~ 5 hours, affects manufacturing schedule.
There is the possibility destroying device body coating when 3. removing peelable welding resistance glue, device can be caused to scrap.
4. the hand-held tweezers gripping element of operating personnel carries out warding off tin clamping and too tightly understands damage device coating, and too pine then easily causes device to fall into tin pot, causes device to scrap.
Utility model content
For problems of the prior art, the utility model provide a kind of go between for half hidden SOP remove gold, ward off tin frock, its structure is simple, easy to operate, highly effective and safe, meets high reliability quality and the capacity requirements of the upper welding equipment 3DPlus device of space product.
The utility model is achieved through the following technical solutions:
What go between for half hidden SOP removes gold, wards off a tin frock, comprises reverse locking forceps-shaped handle and device accommodates protective cover; Device accommodates protective cover and comprises symmetrically arranged two parts folder; Described reverse locking forceps-shaped handle comprises forward tweezer arm and reverse tweezer arm; Two symmetrically arranged forward tweezer arm one end are fixedly connected with, and the other end separately forms herringbone structure; Two reverse tweezer arms are arranged crosswise, and one end is connected with a point beginning for the forward tweezer arm of homonymy respectively, and the other end connects the folder of homonymy respectively; When frock be in do not accommodate state time, the distance between folder is less than the minimum dimension that device goes between on direction at half hidden SOP.
Preferably, the blessing face of folder is provided with the groove coordinated with device, groove lower end wall thickness is less than half hidden SOP and goes between the distance of device surface.
Preferably, reverse locking forceps-shaped handle adopts stainless steel to make.
Preferably, device blessing protective cover adopts polytetrafluoroethylplastic plastic to make.
Preferably, forward tweezer arm and reverse tweezer arm are integrated setting.
Preferably, accommodate protective cover to locking forceps-shaped handle and device to be fixedly connected with by screw and nut.
Compared with prior art, the utility model has following useful technique effect:
The utility model utilizes the reverse locking forceps-shaped handle arranged to be provided in without the blessing power to device under operation by the restoring force of self, utilize device to accommodate protective cover to realize the protection of device and the control of distance, can eliminate the work step smearing peelable welding resistance glue, each device is saved time 4 minutes; Avoid using peelable welding resistance glue, avoid smear peelable welding resistance glue stain can cause gold on device wire, to ward off tin thorough, affects the problem of soldering reliability; Eliminate 4 ~ 5 hours peelable welding resistance adhesive curing time, enhance production progress; The possibility destroying device body coating is there is when thoroughly having stopped to remove peelable welding resistance glue; Each device is saved and is removed 1 minute peelable welding resistance glue time; Reduce the requirement of operating personnel's operative skill, stopped damage device and device and fallen into the possibility that tin pot causes scrapping; The golden success rate of going of device is made to bring up to 100% by former 97%.
Further, by the setting of fit, can better device be realized screens and fixed while blessing, ensure that its reliability accommodated, and the effect of restriction site can be reached by groove.
Further, device accommodates protective cover and adopts polytetrafluoroethylplastic plastic to make, and polytetrafluoroethylplastic plastic is high temperature resistant on the one hand, can not melt, is out of shape at 260 DEG C of tin pot; Secondly polytetrafluoroethylplastic plastic is more soft can not damage device overlay coating; 3rd polytetrafluoroethylmaterial material is the non-conductor of heat, can play heat-blocking action, make operating personnel's non-scald on hand in the operating process of hand-held reverse forceps-shaped handle.
Accompanying drawing explanation
Fig. 1 is the structural representation of frock described in the utility model.
Fig. 2 is the using state figure of frock described in the utility model.
In figure: 1 is reverse locking forceps-shaped handle; 2 is device blessing protective cover; 3 is 3D-PLUS device, and 11 is forward tweezer arm, and 12 is reverse tweezer arm.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, described in be to explanation of the present utility model instead of restriction.
As shown in Figure 1, the utility model is made up of two parts: reverse locking forceps-shaped handle 1 and device clamping protective cover 2.Reverse locking forceps-shaped handle 1 is made up of stainless steel, and device clamping protective cover 2 is made up of polytetrafluoroethylplastic plastic.First the method for machining is adopted to make with polytetrafluoroethylplastic plastic block according to the size of device; Secondly the method for machining is adopted to make with the thick stainless-steel sheet of 1.2mm; Finally adopt screw-nut device to be clamped protective cover 2 to be fixed on reverse locking forceps-shaped handle 1.Reverse locking forceps-shaped handle 1 can make operator exert oneself gripping element without the moment in the process of warding off tin, avoids causing device to fall into Xi Guozhong because of hand pine power.Wherein device clamping protective cover 2 adopts polytetrafluoroethylplastic plastic to make and mainly contains two reasons, and polytetrafluoroethylplastic plastic is high temperature resistant on the one hand, can not melt, is out of shape at 260 DEG C of tin pot.Secondly polytetrafluoroethylplastic plastic is more soft can not damage device overlay coating.3rd polytetrafluoroethylmaterial material is the non-conductor of heat, can play heat-blocking action, make operating personnel's non-scald on hand in the operating process of hand-held reverse locking forceps-shaped handle 1.
Frock described in the utility model is the reverse locking forceps-shaped handle 1 with 3D-PLUS apparatus protective device; clutch reverse locking forceps-shaped handle 1; device can be clamped protective cover 2 to open; after device being put into device clamping protective cover 2; unclamp reverse locking forceps-shaped handle 1 device can be clamped firm; and its side body Gold plated Layer and lead leg root are protected, to avoid warding off in tin process tin material and pollute device body and rise to lead-in wire root and cause short company.This frock has the advantages such as easy to operate, efficiency is high, protected effect is good.
