Abstract

An encapsulation method of electronic components comprises steps as follows: preparing electronic components with cylindrical bodies wherein a cylindrical body has front and rear ends made of metals and a middle end made of ceramics and the front end or the rear end features an outer diameter greater than the middle end of the cylindrical body; preparing a mould consisting of upper and lower moulds; encasing the cylindrical bodies inside the upper and lower moulds, injecting heated and softened protective materials into the mould in which protective materials as protective layers are coated on the cylindrical bodies; injecting the cylindrical bodies removed from the upper and lower moulds into a roller in which excessive protective layers on the front and rear ends of the cylindrical bodies are de-coated.
