7. Coating
1. A crack may be caused in the capacitor due to the stress
8. Die Bonding/Wire Bonding (GMA or GMD Series)
1. Die Bonding of Capacitors
Notice
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 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.
• Use the following materials for the Brazing alloys:
• Mounting

Au-Sn (80/20) 300 to 320 degree C in N
(1) Control the temperature of the substrate so it
(2) Place the brazing alloy on the substrate and place

gently apply the load. Be sure to complete the
operation within 1 minute.

2. Select a resin that is less hygroscopic.
2. Wire Bonding
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.
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.
• Wire
• Bonding
Gold wire: 25 micro m (0.001 inch) diameter
(1) Thermo compression, ultrasonic ball bonding.
(2) Required stage temperature: 150 to 200 degree 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.
