Description
Technical field：
The present invention relates to technical field of semiconductor encapsulation, in particular to a kind of BGA molding dies.
Background technology：
In the MOLDING techniques of semiconductor packages, due to the particularity of baseplate material, the base of different manufacturers different model
The control accuracy of its portion size of plate can not meet the requirement of encapsulation.Substrate is exactly pcb board in fact, and many sizes are merely able to accomplish
± 0.1mm or so.In MOLDING techniques, because its material epoxy resin smallest particles is less than this size, plastic packaging material be present and overflow
The problem of going out, equipment can not automatic jobs.
The measure taken at present is that the substrate of different batches controls its size by changing eccentric pilot pin to compensate, really
The smallest particles that gap is less than epoxy resin is protected, equipment being capable of automatic job.Prior art (is had using the positioning method of cam pin
Body application reference publication No. is a kind of technological document of CN104552672A BGA molding dies), although in BGA molding dies
Positioning in, the needle point width of existing eccentric pilot pin can be changed according to the installation pin hole of pilot pin and processed, but be existed
The problem of be that each pilot pin of changing is both needed to carry out dismounting to mould to ressemble, also exist while taking and assemble wrong appearance
Other problems etc., eccentric pilot pin processing request is high in addition, and cost is high.
In order to solve the above technical problems, the application for a patent for invention that application publication number is CN104552672A discloses one kind
