–

Caution Apply only one kind of soldering condition to a device, except for "partial heating method", or the

device will be damaged by heat stress.

Type of Through-hole Device

µPC4556C: 8-pin plastic DIP (7.62 mm (300))

Process

Conditions

Wave Soldering

(only to leads)

Solder temperature: 260°C or below,

Flow time: 10 seconds or less.

Partial Heating Method

Pin temperature: 300°C or below,
