Description

Cream brushing device for silicon wheat production

Technical Field

The utility model relates to a brush cream field especially relates to a brush cream device is used in silicon wheat production.

Background

In the manufacturing process flow of the semiconductor microphone Si-MIC (so-called silicon microphone) in the electronic manufacturing industry at present, the mainly adopted method is the centralized manufacturing method: namely, a PCB integrated with a plurality of single silicon microphones (Si-MIC) PADs is used as a unit for processing and manufacturing, and then each single silicon microphone PAD is processed in turn according to the process flow: pasting, reflow soldering, welding, curing, dispensing solder paste and the like, and then: and (4) pasting a shell, reflowing, cutting, testing, packaging and the like, and finally finishing manufacturing. Among the above various process flows, "solder paste dispensing and case attaching" belong to the post-process (i.e., the process flow that is performed later in the whole manufacturing process flow). The 'shell sticking' is used for protecting a core microchip (such as a Micro Electro Mechanical System (MEMS)) and a core component in the single silicon microphone, and is an important step for finishing a qualified product, and the 'shell sticking' is a necessary condition for finishing the 'shell sticking', so that a 'shell' can be firmly stuck on copper foil on the periphery of the single silicon microphone only through the tin paste (the tin paste in a natural state has viscosity, but becomes hard and firm after being heated and baked through reflow soldering), and the 'shell sticking' is a very important link in a manufacturing process flow of the Si-MIC and is a key step which is required to be finished by the product. The process content of the 'solder paste spot' is that solder paste with a proper thickness is uniformly coated on the copper foil at the edge of a 'single silicon microphone (Si-MIC)', and the main method for completing the process flow in the current electronic manufacturing field is as follows: the glue is dispensed one by one through a glue dispenser (namely, the glue dispenser is used for dispensing the tin paste on the copper foil at the edge of the 'single silicon microphone (Si-MIC)', the speed of the process flow is limited, so that the production efficiency of the silicon microphone is low, and the tin paste is wasted greatly.
