Abstract

The utility model relates to a shrink protection pad of PCB board, especial PCB board package case filler material that relates to. The body is dull and stereotyped foam, is covered with the incision of horizontal setting on the body, and the notched opening of adjacent lines in opposite directions or mutually the back of the body set up, above -mentioned incision is crescent. The utility model discloses a benefit is that this structural design can effectively prevent to print the situation that transit that board vanning rear cabinet inner gap caused greatly damaged.

Description

The contraction neonychium of pcb board

Technical field

The utility model relates to pcb board packaging facilities, relates to pcb board lodge packing material especially.

Background technology

Pcb board is exactly printed circuit board (PCB), almost appears in the middle of each electronic machine.And electronic component is just set on the pcb board of different sizes.Along with electronic machine becomes increasingly complex, the part of needs gets more and more, the circuit on pcb board and part also more and more intensive.This plate is by insulated heat and unbending material forms substrate, the tiny line material can seen on surface is Copper Foil, originally Copper Foil covers on whole plank, and part is disposed by etching in the fabrication process, and the part stayed just becomes webbed tiny circuit.These circuits are referred to as wire or claim wiring, and the circuit being used to provide part on pcb board connects.One piece of pcb board is except fixing various little electronic component, and its radical function provides the mutual electrical connection of various electronic component in addition.Along with the development of information techenology, electronic machine also becomes increasingly complex, and the part of needs gets more and more, the circuit on pcb board and part also more and more intensive.In pcb board manufacturing, pcb board is by insulated heat and unbending material forms substrate, the tiny line material can seen on surface is Copper Foil, originally Copper Foil covers on whole plate, part is disposed by etching in the fabrication process, the part stayed just becomes webbed tiny circuit, and these circuits are referred to as wire, and for providing the circuit of part on pcb board to connect.

Vanning is needed after existing pcb board inner wrapping; because pcb board model is many; size also has varied; the carton size of the concentrated common-use size that printed board manufacturer normally customizes when formulating carton; most printed board still has gap after vanning; usual manufacturer adopts the regular foam on market fill up or do not adopt any safety method; be easy to cause foam pad to recycle; poor quality foam scrap contaminated environment produces electrostatic, or is easy to cause mutual collision and extrude thus cause in transport transfer process scrap.

Utility model content

The utility model object is to provide a kind of contraction neonychium of easy to process, pcb board that result of use is good.

The technical scheme realizing the utility model object is as follows: a kind of contraction neonychium of pcb board, and body is flat plastic foam, body is covered with the otch of horizontally set, and the opening of adjacent lines otch in opposite directions or opposing setting, and above-mentioned otch is crescent.Above-mentioned otch transverse pitch is 3 ~ 5mm.

This novel benefit is this structure design can effectively prevent printed board from casing situation damaged in transit that rear cabinet internal clearance causes greatly; And printed board packing contaminated environment can be prevented, improve the safety of Product transport process.

Accompanying drawing explanation

Fig. 1 is the utility model schematic diagram.

Detailed description of the invention

See Fig. 1, a kind of contraction neonychium of pcb board, body is flat plastic foam, body is covered with the otch 1 of horizontally set, and the opening of adjacent lines otch in opposite directions or opposing setting, and above-mentioned otch is crescent.Above-mentioned otch transverse pitch is 3 ~ 5mm, and the line space that otch is arranged in opposite directions is less, and the line space of the opposing setting of otch is according to the space requirement adjustment of packaging casing.

See Fig. 2, well-regulatedly on original flat plastic foam during this novel concrete enforcement open crescent otch, form well-regulated array form.Utilize the characteristic of regular crescent moon otch and plate foam, make it have significantly contractibility, after the flat plastic foam tensile of incision operation extends, have engraved structure 2, be packed in packing chest, elasticity is better.This novel situation damaged in transit that can effectively prevent printed board vanning rear cabinet internal clearance from causing greatly, and the generation of electrostatic between product can be effectively prevent, reduce packing to the pollution of environment.

Obviously, above-mentioned detailed description of the invention of the present utility model is only for the utility model example is clearly described, and is not the restriction to the utility model embodiment.For those of ordinary skill in the field, can also be easy to make other pro forma change on the basis of the above description or substitute, and these change or substitute and also will be included within protection domain that the utility model determines.

Claims

1. the contraction neonychium of a pcb board; body is flat plastic foam; it is characterized in that: the otch (1) body being covered with horizontally set; and the opening of adjacent lines otch in opposite directions or opposing setting; above-mentioned otch is crescent, and is rendered as engraved structure (2) when being stretched to using state.

2. the contraction neonychium of pcb board according to claim 1, is characterized in that: above-mentioned otch transverse pitch is 3 ~ 5mm.
