Description

technical field [0001] The invention relates to the technical field of optoelectronic element packaging, in particular to a high impact-resistant silicone adhesive for SOP packaging optocouplers. Background technique [0002] Optical coupler (optical coupler) is a kind of light as the medium, the input electrical signal drives the LED, emits light of a certain wavelength, is received by the photodetector to generate photocurrent, and then amplified and output to complete the electrical-optical-electrical conversion new equipment. The packaging form is mainly small patch package (SOP). [0003] The type of adhesive determines the performance of the optocoupler device. The usual adhesive is resin type. The signal inside the optocoupler is transmitted through light. The resin adhesive is required to have well-matched spectral characteristics to avoid the loss of optical radiation. The resin-type adhesive has the properties of isolation voltage, insulation and voltage resistan...
