Description
Technical field
The present invention relates to ceramic pin grid array skinning technique field, draws more particularly to a kind of ceramic pin grid array surgeon's needle
Line protects pad.
Background technology
Ceramic pin grid array shell（Ceramic Pin Grid Array Packages, abbreviation CPGA）It is ultra-large
The most frequently used inserting packing forms of integrated circuit, good with packaging density height, electric heating property, air-tightness is good, the spy such as reliability height
Point.Conventional lead pitch is 2.54mm is regularly arranged, 2.54mm is staggered, 1.27mm is regularly arranged, the regular rows of 1.00mm
Row, it can meet that high-density packages, system integration encapsulation etc. require, be mainly used in encapsulating the VLSI cores such as CPU, DSP, CCD, ASIC
Piece.
It is arranged on using the packaged device of ceramic pin grid array shell by the inserting of pin lead in printed board, plays interconnection
And supporting role, because pin lead needs insertion installation corresponding with PCB interconnected pores, therefore lead deformation or damage can not expire
Foot installs and uses requirement.
But during ceramic pin grid array shell production, transmission, packaging and testing etc., pin lead is highly susceptible to outer
Power causes lead deformation or damage, has a strong impact on that product uses.
The content of the invention
The technical problem to be solved in the present invention is to be directed to above-mentioned the deficiencies in the prior art, there is provided outside a kind of ceramic pin grid array
Shell pin pilot protection pad, solve ceramic pin grid array shell production, transmit, during packaging and testing pin lead deformation or
The problem of damage causes product not use, have in ceramic pin grid array shell during production, transmission, packaging and testing
Protect the characteristics of pin lead is without damage, product quality stability is good.
In order to solve the above technical problems, the technical solution used in the present invention is：A kind of ceramic pin grid array surgeon's needle draws
Line protects pad, including insulation spacer, and the insulation spacer is provided with the through hole of protection pin lead, the through hole number and position and
The number of ceramic pin grid array surgeon's needle lead is corresponding with position.
Preferably, the insulating gasket material is polytetrafluoroethylene (PTFE).
Preferably, the insulation spacer is cuboid insulation spacer.
Preferably, the seamed edge of the cuboid insulation spacer is chamfering.
Preferably, the via depth is less than the length of ceramic pin grid array surgeon's needle lead.
Preferably, the insulation spacer center is provided with the cavity structure for being easy to ceramic pin grid array shell inserting.
Preferably, the through-hole diameter is more than the external diameter of ceramic pin grid array surgeon's needle lead.
Preferably, the insulation spacer thickness is less than 20 millimeters.
It is using beneficial effect caused by above-mentioned technical proposal：The present invention is by designing ceramic pin grid array surgeon's needle
Pilot protection pad, including insulation spacer, insulation spacer are provided with the through hole of protection pin lead, through hole number and position and ceramic pin
The number of grid array surgeon's needle lead is corresponding with position.Due to through hole number on pad and position and ceramic pin grid array shell
The number of pin lead is corresponding with position, therefore the pin lead on ceramic pin grid array shell can fully enter corresponding through hole
In, pin lead is inserted in the through hole on pad during the production, transmission, packaging and testing of ceramic pin grid array shell,
Due to pin lead in through-holes, thus pad can by pin lead and it is extraneous isolate, play a part of protecting pin lead, when need by
Pad is removed and can installed when being arranged in printed board by ceramic pin grid array shell.Ceramics are realized by this technological means
Pin grid array shell production, transmit, pin lead is isolated from the outside without damage during packaging and testing, improve the matter of product
Amount.
Brief description of the drawings
Fig. 1 is the structural representation of the ceramic pin grid array surgeon's needle pilot protection pad of the present invention.
In figure：1st, insulation spacer；2nd, through hole.
Embodiment
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description, but the protection model of the present invention
Enclose be not limited to it is as described below.
As shown in figure 1, being the structural representation of the ceramic pin grid array surgeon's needle pilot protection pad of the present invention, including insulate
Pad 1, insulation spacer 1 are provided with the through hole 2 of protection pin lead, 2 numbers of through hole and position and ceramic pin grid array surgeon's needle lead
Number it is corresponding with position.
Pin lead is inserted into leading on pad during the production, transmission, packaging and testing of ceramic pin grid array shell
In hole 2, because pin lead is in through hole 2, therefore pin lead and extraneous isolation can be played a part of protecting pin lead by pad,
Pad is removed and can installed when needing ceramic pin grid array shell being arranged in printed board.Pass through this technological means
It is without damage to realize that ceramic pin grid array shell pin lead during production, transmission, packaging and testing is isolated from the outside, improves
The quality of product.
In one embodiment of the present of invention, the material of insulation spacer 1 is polytetrafluoroethylene (PTFE), polytetrafluoroethylene (PTFE) have high lubrication,
Easy processing, inexpensive, antiacid alkali resistant, high temperature resistant, resist the features such as various organic solvents, insulation spacer 1 made using polytetrafluoroethylene (PTFE),
It can ensure that insulation spacer 1 does not deform and damaged in use, strengthen ceramic pin grid array surgeon's needle pilot protection
The stability that pad uses.
In one embodiment of the present of invention, insulation spacer 1 is cuboid insulation spacer 1, and insulator is set to rectangular shape,
It is easy to the processing of insulating trip.
