Row, can meet that high-density packages, system integration encapsulation etc. require, be mainly used for encapsulating the VLSI cores such as CPU, DSP, CCD, ASIC
Piece.
It is installed 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, since pin lead needs insertion installation corresponding with the interconnected pores of PCB, 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, seriously affects product use.
Utility model content
The technical problems to be solved in the utility model is in view of the above shortcomings of the prior art, there is provided a kind of ceramic pin grating array
Row surgeon's needle pilot protection gasket, solves ceramic pin grid array shell pin lead during production, transmission, packaging and testing and becomes
The problem of shape or damage cause product not use, has in ceramic pin grid array shell in production, transmission, packaging and testing
The characteristics of pin lead is without damage, product quality stability is good is protected in journey.
In order to solve the above technical problems, technical solution adopted in the utility model is：A kind of ceramics pin grid array shell
Pin pilot protection gasket, including insulation spacer, the insulation spacer are equipped with the through hole of protection pin lead, the through hole number and position
Put 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 equipped with the cavity structure easy to ceramic pin grid array shell inserting.
Preferably, the through-hole diameter is more than the outside 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 utility model is by designing outside ceramic pin grid array
Shell pin pilot protection gasket, including insulation spacer, insulation spacer are equipped with the through hole of protection pin lead, through hole number and position and pottery
The number of porcelain pin grid array surgeon's needle lead is corresponding with position.Due to through hole number on gasket and position and ceramic pin grid array
The number of surgeon's needle lead is corresponding with position, thus the pin lead on ceramic pin grid array shell can fully enter it is corresponding
In through hole, by the through hole of pin lead insertion pad on piece during the production, transmission, packaging and testing of ceramic pin grid array shell
In, due to pin lead in through-holes, gasket can by pin lead and it is extraneous isolate, play the role of protecting pin lead, when needing
Gasket is removed and can installed when ceramic pin grid array shell is installed in printed board.Realized by this technological means
Ceramic pin grid array shell production, transmit, pin lead is isolated from the outside without damage during packaging and testing, improve product
Quality.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model ceramics pin grid array surgeon's needle pilot protection gasket.
In figure：1st, insulation spacer；2nd, through hole.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description, but the utility model
Protection domain be not limited to it is as described below.
As shown in Figure 1, be the structure diagram of the utility model ceramics pin grid array surgeon's needle pilot protection gasket, including
Insulation spacer 1, insulation spacer 1 are equipped with the through hole 2 of protection pin lead, 2 numbers of through hole and position and ceramic pin grid array surgeon's needle
The number of lead is corresponding with position.
By the logical of pin lead insertion pad on piece during the production, transmission, packaging and testing of ceramic pin grid array shell
In hole 2, since pin lead is in through hole 2, pin lead and extraneous isolation can be played the role of protecting pin lead by gasket,
Gasket is removed and can installed when needing ceramic pin grid array shell being installed 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 utility model, 1 material of insulation spacer is polytetrafluoroethylene (PTFE), and polytetrafluoroethylene (PTFE) has Gao Run
