Notice

1. A crack may be caused in the capacitor due to the stress

of the thermal contraction of the resin during curing

process.

The stress is affected by the amount of resin and curing

contraction.

Select a resin with small curing contraction.

The difference in the thermal expansion coefficient

between a coating resin or a molding resin and the

capacitor may cause the destruction and deterioration of

the capacitor such as a crack or peeling, and lead to the

deterioration of insulation resistance or dielectric

breakdown.

Select a resin for which the thermal expansion coefficient

is as close to that of capacitor as possible.

A silicone resin can be used as an under-coating to buffer

against the stress.

2. Select a resin that is less hygroscopic.

Using hygroscopic resins under high humidity conditions

may cause the deterioration of the insulation resistance of

a capacitor.

An epoxy resin can be used as a less hygroscopic resin.

7. Coating

1. Die Bonding of Capacitors

• Use the following materials for the Brazing alloys:

Au-Sn (80/20) 300 to 320

°C in N2 atmosphere

• Mounting

(1) Control the temperature of the substrate so it

matches the temperature of the brazing alloy.

(2) Place the brazing alloy on the substrate and place

the capacitor on the alloy. Hold the capacitor and

gently apply the load. Be sure to complete the

operation within 1 minute.

2. Wire Bonding

• Wire

Gold wire: 25 micro m (0.001 inch) diameter

• Bonding

(1) Thermo compression, ultrasonic ball bonding.

(2) Required stage temperature: 150 to 200

°C

(3) Required wedge or capillary weight: 0.2N to 0.5N

(4) Bond the capacitor and base substrate or other

devices with gold wire.

8. Die Bonding/Wire Bonding (GMA or GMD Series)
