Abstract
The utility model discloses a jig of a subminia-ture tube (SMT) product repairing device, which comprises a bottom support mechanism, wherein the bottom support mechanism comprises a bottom tuyere bayonet and a support top tray fixed on the tuyere, the bottom tuyere is provided with a wind baffle clamping piece, a support screw rod is connected between the wind baffle clamping piece and the support top tray, and a nut is arranged on the support screw rod. When a B ball grid array (BGA) component is repaired, the deformation quantity of a printed circuit board assembly (PCBA) is greatly reduced, the primary repairing success rate of the BGA component is more than 95%, and the jig is suitable for all BGA component repairing devices on the PCBA, so that the production cost is reduced, and the resource is saved.
Description
Technical field
The utility model relates to the SMT product and reprocesses device, specifically be meant a kind of to (the Ball Grid Array ball grid array structure of the BGA in the SMT product, be a kind of packaged type that integrated circuit adopts organic support plate) when carrying out reclamation work, cooperate the tool of reprocessing device.
Background technology
At present, during to the BGA reclamation work in all SMT products, all be to adopt the mode of localized heating that the BGA element is heated, will cause the temperature difference between BGA element and the PCBA like this, owing to the reason of expanding with heat and contract with cold, make the difference of expanding with heat and contract with cold of the generation at the different position of PCBA, simultaneously PCB is in that be heated also can softening transform, therefore when reprocessing the BGA element, PCBA is bound to produce distortion, different PCBA is varying in size of deflection only, and the phenomenon of empty weldering or short circuit can appear in the change when reprocessing welding of BGA element like this.The yield that makes the BGA element reprocess reduces greatly.
Reprocess low this problem of yield if solve the BGA element at present, must make special-purpose smelting tool at each PCBA.Existing technology is utilized BGA to reprocess the BGA element that platform reprocesses needs and is reprocessed, if once unsuccessfully carry out reprocessing second time, till the PCBA subscription rate again.Its shortcoming is: a) scrappage of PCBA is bigger, directly for factory causes production loss, strengthens production cost; B) too much making smelting tool (a PCB makes a smelting tool) improves production cost;
The utility model content
The problem that the utility model need solve provides a kind of PCBA of avoiding distortion and causes that the BGA element reprocesses the tool that yield is low, SMT product that save cost is reprocessed device.
To achieve these goals, the utility model is designed the tool that a kind of SMT product is reprocessed device, comprise bottom support mechanism, described bottom support mechanism comprises that bottom tuyeres air port bayonet socket and the support that is fixed on the air port take over a business, described bottom tuyeres is provided with the card that keeps out the wind, between keep out the wind card and support are taken over a business, be connected with studdle, nut is installed on studdle.And screw flight just with bottom tuyeres keep out the wind card hold-down nut match, can directly install.And realize supporting the function of free adjustment height by rotary screw.
Continuous screw rod and the bottom tuyeres type that is in line is taken over a business in described support, and vertical mutually.
Continuous studdle is taken over a business in described support and bottom tuyeres is provided with screw thread, and studdle realizes that with bottom tuyeres turn is connected.
The screw rod that described support takes over a business to be connected is fixedly connected, and vertical mutually.
The utility model SMT product is reprocessed the tool of device by but the bracing or strutting arrangement of a free adjustment height is installed on bottom tuyeres, can require to regulate according to reality simultaneously and highly support, make BGA reprocess platform and carrying out the BGA element when reprocessing, the PCBA deflection reduces greatly, simultaneously BGA element repair for 1st time success rate is reached more than 95%, and be applicable to the device that the BGA element on all PCBA is reprocessed, therefore reduced production cost, saved resource.The tool that the utility model SMT product is reprocessed device reduces the deflection of PCBA, stops factory because of a in the past PCBA of cancellation that scraps that the PCBA distortion produces makes a smelting tool, saves a large sum of smelting tool manufacturing cost.
Description of drawings:
Fig. 1 is the jig structure schematic diagram that the utility model SMT product is reprocessed device.
Embodiment
For the ease of those skilled in the art's understanding, structural principle of the present utility model is described in further detail below in conjunction with specific embodiment and accompanying drawing:
As shown in Figure 1, a kind of SMT product is reprocessed the tool of device, comprise bottom support mechanism, described bottom support mechanism comprises that bottom tuyeres bayonet socket 1 and the support that is fixed on the air port take over a business, described bottom tuyeres is provided with the card 2 that keeps out the wind, between keep out the wind card 2 and support take over a business 5, be connected with studdle 4, nut 3 is installed on studdle 4.And screw flight just with bottom tuyeres keep out the wind card hold-down nut match, can directly install.And realize supporting the function of free adjustment height by rotary screw.The screw rod that described support takes over a business to be connected is fixedly connected, and vertical mutually.5 studdles that link to each other 4 and the bottom tuyeres type that is in line is taken over a business in described support, and vertical mutually.Described support is taken over a business 5 studdle and the bottom tuyeres that link to each other and is provided with screw thread, and studdle 4 realizes that with bottom tuyeres turn is connected.
Operation principle of the present utility model: during use that the air port bayonet socket 1 of supporting mechanism and the snap ring reprocessed on the heat-generating system of platform bottom is stuck mutually, the phenomenon of left rotation and right rotation can not be arranged.Before adjusting bearing height, the PCBA that will reprocess is put into anti-BGA and reprocesses on the anchor clamps of platform and clip earlier, again the BGA element is moved on to the bottom support system directly over, and check the height that supports apart from the PCBA base plate.Adjust when supporting height, the Luo bar is supported in turn slowly, allow as the support and the PCBA base plate at a distance of 2-3MM (having element then to be as the criterion) with element as the bottom, because PCBA is the meeting softening transform after being heated, simultaneously owing to the temperature difference and the reason of expanding with heat and contract with cold, the residing position of BGA element deflection maximum, simultaneously owing to heavy reason, PCBA is bound to be out of shape downwards, after PCBA is deformed to certain Cheng Du downwards, support is taken over a business and PCBA can be propped up, and makes the BGA element be in a relative plane and is heated and reprocesses welding.If support is taken over a business directly PCAB bottom dieback, be heated owing to expand with heat and contract with cold as PCBA, PCBA can produce internal stress, simultaneously BGA reprocess platform anchor clamps firmly PCBA clamp, PCBA can't be out of shape downwards have to be to the distortion of arching upward.Therefore when supporting height, adjusting the PCBA bottom can be made extremely full scarcely.If the PCBA plate of extra large size also can add the support system that board carries, effect can be better like this.Because PCBA is when being heated, not only the tile position at BGA element place can be out of shape, and other position can be out of shape equally, simultaneously can large deformation also can be big more more along with the PCBA area, at this moment not only to control the distortion of the not piece position at BGA element place, also will control the deflection of whole PCBA simultaneously.
Foregoing is preferred embodiment of the present utility model only, is not to be used to limit embodiment of the present utility model, and those skilled in the art are according to design of the present utility model, and appropriate adaptation of having done or modification all should be within protection ranges of the present utility model.
