Heat conduction paste is mainly used for heat dissipation, mainly filling between the CPU and the heat sink in order to play the expected heat dissipation performance, avoid the CPU can not timely heat dissipation and burn, this material presents the paste state, without waiting for solidification can be carried out the next construction. Some users found that the properties of thermal silicone grease are sticky and will not be constructed during construction. Can you dilute it by yourself?
1. The problem of slurry outflow when sizing is stopped Cause analysis: usually hand pressure glue gun is through the glue guns to pressure, the driveshaft forward and make the mucilage out to complete the construction process, it is to choose a thin bottle series of products, so in the process of the glue bottle can produce certain expansion, due to stress, such as in use process, if only to stop on the pressure of the glue guns, thin bottle by the recovery of expansion and contraction of the original, plus glue guns "drive shaft" inertia and thrust forward, even if the glue gun to stop pressure, cement glue will continue to drain, so can bring inconvenience to be subcontracted, more will affect construction quality.
Silicone potting sealant is commonly used as heat conduction, heat dissipation, sealing, and seismic materials in electronic components. Heat conduction sealing refers to the pasting of all components on the PCB circuit board so that the heat generated on the components of the PCB can quickly spread to the external thermal conductive substrate (aluminum or thermal ceramics, etc.) through the heat conduction sealing glue, and finally directly transferred to the external environment.
Electronic potting glue will encounter a variety of problems in the construction, after all, electronic potting glue belongs to chemicals, in the construction by temperature, water vapor and operation process and other reasons, resulting in a lot of problems. Understanding these reasons will help to smooth the construction and avoid rework.
Operation tools: acetone, toothbrush, washbasin, rag, toilet paper. Operation steps:
The important properties of adhesives include rheological properties (viscosity, thixotropy, collapse-resistance and tail-dragging, storage life/condition and effective life) and mechanical properties (viscosity, mechanical strength and heat resistance, curing period, electrical stability, etc.)
