Description

Capping jig Technical Field The utility model relates to the technical field of chip packaging, in particular to a sealing cover jig. Background Common packaging forms in the field of integrated circuit packaging are ceramic packages and plastic packages. For example, in the ceramic packaging process of a radio frequency power device, a tube shell and a cover plate are mostly used in a sealing process, the interior of the tube shell is used for arranging various chips and bonding wires so as to realize a circuit with a specific function, the cover plate wraps the tube shell, and the cover plate with a glue coating and a soldering lug has the effect of physically protecting the tube shell and preventing external pollution, impact, water vapor, temperature and other external environments, so that the sealing cover is focused on firmness, air tightness and universality. At present, two methods are mainly used for sealing the tube shell. The first is manual capping and the second is professional capping machine capping. The manual capping process generally comprises the steps of firstly placing a cover plate with a glue or a soldering lug right above a tube shell by using a tool such as tweezers to find the position of the corresponding cover plate, then clamping the tube shell and the upper and lower sides of the cover plate by using a clamp, ensuring that the glue or the soldering lug is continuously attached to the tube shell after being melted, finally placing the tube shell or the soldering lug in a heating table or a baking oven for baking, setting a corresponding temperature curve in the baking oven according to the type of the cover plate to achieve the optimal curing effect, and firmly bonding the tube shell and the cover plate together after baking is finished. The manual sealing cover has the defects that the cover plate is placed according to naked eyes and hand feeling, the position deviation of the cover plate and the hand feeling is large, the pressure exerted by the cover plate cannot be quantified, the product is damaged due to the fact that the cover plate is touched by people by mistake, the manual efficiency is low, and the manual operation cannot realize mass production. The process of sealing by the professional capping machine generally comprises the steps of firstly placing a tube shell into a tube shell fixing pit of a capping device to confirm that the position state of the tube shell is correct, then placing a cover plate with glue or soldering lug into a cover plate fixing jig of the capping device to confirm that the placement state of the cover plate is correct, and finally folding the tube shell and carriers on two sides of the cover plate to run a formulated program. The special capping machine has the advantages of complex structure, inconvenient die replacement and high design, manufacture and maintenance cost, and solves the problems of low manual capping efficiency and low yield. Therefore, improving the capping efficiency and capping economy while ensuring the capping quality is a process issue that engineers and technicians are urgent to address.
