°C or below, Flow time: 10 seconds or less,

WS60-00-1

Maximum number of flow processes: 1 time,

Pre-heating temperature: 120

°C or below (Package surface temperature).

Partial heating method

Pin temperature: 300

°C or below,

–

Heat time: 3 seconds or less (Per each side of the device).

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

µPC4742C: 8-pin plastic DIP (300 mil)

Process

Conditions

Wave soldering

Solder temperature: 260

°C or below,

(only to leads)

Flow time: 10 seconds or less.

Partial heating method

Pin temperature: 300

°C or below,

Heat time: 3 seconds or less (per each lead).

Caution For through-hole device, the wave soldering process must be applied only to leads, and make

sure that the package body does not get jet soldered.
