Abstract

PURPOSE:To improve punching ability remarkably, eliminate paper chips and peculiar whiskers and thereby prevent chips from raising from carrier tape and, consequently, from detaching therefrom upon chip mounting by mixing together thermoplastic resin and inorganic filling agent in specific amounts. CONSTITUTION:Chip mounting holes 2 and tape feed holes 3 are punched through a tape at 4mm pitches by a punch metal die to obtain a chip carrier tape 1. Of the thermoplastic resins for use in the manufacture of the tape, polypropylene is preferable from the viewpoint of availability. As an inorganic filling agent, powdered calcium carbonate is easily available at low prices. The thermoplastic resin and the inorganic filling agent are mixed together in an amount of 40-90 pts.wt. and 60-10 pts.wt., respectively. If the inorganic filling agent exceeds this range, although the punching ability is improved, the use of such a filling agent is objectionable, since it may cause the failure to attach cover tape and bottom tape to a product tape or damages thereto upon tape rolling on a reel. If the inorganic filling agent is within a smaller part weight range than the aforesaid, plastic whiskers and torn punching edges, although not so much as in the case of the paper, are produced. The punching ability is also lowered.

The present invention relates to the punched chip carrier tape. Paper and plastic are available as such tape materials, and the present invention is aimed at developing a tape that synergistically combines the economic efficiency of paper with the advantages of plastic.

Paper punching tape is the cheapest, easy to process, and has the advantage of being easy to store and handle by winding on a reel, but because the raw material is pulp, the occurrence of "whiskers" during punching is unavoidable. When mounting chips that have recently become smaller in size, there has been a problem in that the chips may fall off due to the floating phenomenon, causing problems in the mounting work performed by robots. Furthermore,
Paper dust was generated during punching, and the environment was bad, so paper dust had to be removed from the product tape. Furthermore, since it is made of paper, there is a limit to its thickness, and if it is too thick, it will cause delamination during processing and reeling, and a decrease in punching performance due to punching resistance, so it is impossible to obtain a thick paper tape with strong stiffness. The thickness of standard paper tape is 0.
The maximum thickness is 95m, and it is not economically possible to make it thicker than this. Furthermore, there is also the problem that paper does not have sufficient dimensional stability due to the influence of temperature and humidity.
