FIP点胶加工定制

点胶加工（Form-In-Place），简称FIP点胶，是指以[敏感词]的计算机操控自动化设备，将流体橡胶直接点涂在金属或塑料的壳表面，在一定条件下固化，从而形成导电或不导电密封衬垫，以达到EMI屏蔽及环境密封效果。射频模块FIP点胶加工，电磁屏蔽性能可达120dB，工作温度-50-150度，胶条附着力好。

FIP点胶加工的优势：

●非常好的电磁屏蔽效果，从200MHz到10GHz的屏蔽效果超过110dB。

● 直接将导电胶挤在加工件上，没有其他安装工序。

● 节省空间达60%-窄到1.0mm的接触面能够加工。

● 挤出胶料固化后，尺寸的误差在0.1mm以内。

● 对于多种金属和塑料具有良好的粘接性能。

● 可按任意路径生成衬垫，不需昂贵的模具，货物周转快，设计周期短。

● 同模切相比，大大节省原料。

● 导电胶固化后硬度。结构件在装配后，导电胶在高度方向上需要有30%~50%的压缩，才能达到良好的屏蔽效果。导电胶的硬度参数关系到结构件装配时所需要的压力（螺钉的装配密度及装配扭力）。

● 防火等级。导电胶的防火等级从UL94HB~UL94-V0不等。

● 成本考量。不同金属填料的导电胶在成本上差异较大，在满足性能、工艺的前提下，可以选择低成本的导电胶。

FIP adhesive processing customization

Form In Place, abbreviated as FIP dispensing, refers to the precise computer-controlled automation equipment that directly applies fluid rubber onto the surface of metal or plastic shells, solidifies under certain conditions, and forms conductive or non-conductive sealing gaskets to achieve EMI shielding and environmental sealing effects. RF module FIP adhesive processing, electromagnetic shielding performance can reach 120dB, working temperature -50-150 degrees, good adhesive tape adhesion.

Advantages of FIP adhesive processing:

Very good electromagnetic shielding effect, with a shielding effect of over 110dB from 200MHz to 10GHz.

Directly squeeze the conductive adhesive onto the workpiece without any other installation process.

Space saving up to 60% - contact surfaces as narrow as 1.0mm can be processed.

After the extruded rubber material solidifies, the dimensional error is within 0.1mm.

Has good adhesive properties for various metals and plastics.

● Pads can be generated along any path without the need for expensive molds, with fast turnover of goods and short design cycles.

Compared to die-cutting, it greatly saves raw materials.

Hardness of conductive adhesive after curing. After assembly of structural components, the conductive adhesive needs to be compressed by 30% to 50% in the height direction to achieve good shielding effect. The hardness parameter of conductive adhesive is related to the pressure required during the assembly of structural components (the assembly density and assembly torque of screws).

● Fire rating. The fire rating of conductive adhesive varies from UL94HB to UL94-V0.

● Cost considerations. The cost of conductive adhesives with different metal fillers varies greatly, and low-cost conductive adhesives can be selected while meeting performance and process requirements.
