Problems solved by technology

However, the miniature reciprocating cylinder mounted in the suspension of the hard disk unit is very small
If the air volume of the sprayed inert gas is too large, the position of the reciprocating cylinder, which is hard to determine, will change
If the air volume of the sprayed inert gas is too small, the temperature of the inert gas will be uneven

Embodiment Construction

[0022] Refer below Figure 1 to Figure 14 The present invention will be described with respect to the electronic device manufacturing apparatus of the present invention.

[0023] figure 1 It is the suspension 1 of the hard disk drive (HDD) manufactured by the electronic equipment manufacturing apparatus (suspension manufacturing apparatus) 20 of this invention. The hard disk device has a magneto-optical disc that rotates around a main shaft, and a cart that rotates around a fulcrum. arm such as figure 1 The configuration shown is on suspension 1. The suspension 1 has a bottom plate 2 fixed by an arm, a load beam 3 capable of resisting elastic deflection, and a bend 4 of wiring arranged to overlap the load beam 3 .

[0024] The wiring bend 4 includes a metal base 5 composed of a thin stainless steel plate and wiring 6 formed on the metal base 5 . A gimbal portion 7 is formed in the vicinity of the front end 4A of the bend 4 of the wiring, and a slider 8 is mounted on an ar...

Abstract

The invention provides an electronic machine manufacturing device, which is a suspension of a hardware device equipped with a micro reciprocating cylinder, and the electronic components are mounted with high precision through a conductive adhesive. The electronic machine manufacturing device 20 includes a conveyor belt 21, a plurality of heaters 23A, 23B and 23C, a gas supply source 24, a narrow portion 31, and a plurality of guide portions 32A, 32B and 32C. The conveyor belt 21 conveys a workpiece W coated with an uncured adhesive 10. The narrow path portion 31 forms a narrow path 34 along apath Y through which the conductive adhesive 10 passes. The guide portions 32A, 32B and 32C guide the inert gas to flow together in the slit 34, accumulate the heat of the heaters 23A, 23B and 23C, and are provided with the gas dispersing means 40A, 40B and 40C for dispersing the inert gas.

Description

technical field [0001] The present invention relates to an electronic device manufacturing apparatus in which electronic components fixed by a conductive adhesive are mounted with high precision. Background technique [0002] The suspension of the hard disk device is equipped with a miniature reciprocating cylinder, which can drive the magnetic head with high precision. Unlike electronic components such as capacitors, the positional accuracy of the miniature reciprocating cylinder unit, the deviation of the dredging stroke and the influence of resonance characteristics. This can affect long-term bond reliability. Therefore, in the assembly process of the miniature reciprocating motion cylinder unit, not only a highly reliable circuit connection is required, but also a high positional accuracy is required. [0003] The piezoelectric elements that make up the miniature reciprocating cylinder will lose their natural polarization at high temperature, resulting in the loss of p...
