Abstract
Description
technical field
[0001] The invention relates to the field of COB package structure, and more specifically, relates to a light source module with a solder-free COB package structure. Background technique
[0002] The full name of COB packaging is chip-on-board packaging. It is a technology to solve the heat dissipation problem of LED. It is to adhere the bare chip to the interconnection substrate with conductive or non-conductive adhesive, and then perform wire bonding to realize its electrical connection. If the COB package The bare chip is directly exposed to the air, which is easily polluted or artificially damaged, affecting or destroying the function of the chip, so the chip and the bonding wire are encapsulated with glue. People also call this packaging form soft encapsulation.
[0003] COB light source is a high-efficiency integrated surface light source technology that directly pastes LED chips on a mirror metal substrate with high reflectivity. This technology elimi...
