Sleeve soldering device and method of producing electronic device

A sleeve soldering device has a displacement sensor and a heat flux sensor. The displacement sensor detects a physical quantity related to a pressure from a heated sleeve heated by a heater onto an electric board when the heated sleeve presses the electric board. The displacement sensor detects a physical quantity related to a deformation amount of the electric board due to thermal energy from the heater. The heat flux sensor detects a physical quantity related to a heat transfer amount from the heater to the electric board when the heated sleeve is pressed to the electric board. A control part compares each of detection values obtained from the displacement sensor and the heat flux sensor with a respective judgment reference so as to detect whether each detection value satisfies the respective reference.

Ultrasonic-assisted solder transfer

Apparatus and methods are disclosed for transferring solder to a substrate. A substrate belt moves one or more substrates in a belt direction. A decal has one or more through holes in a hole pattern that hold solder. Each of the solder holes can align with respective locations on one of the substrates. An ultrasonic head produces an ultrasonic vibration in the solder in a longitudinal direction perpendicular to the belt direction. The ultrasonic head and substrate can be moved together in the longitudinal direction to maintain the ultrasonic head in contact with the solder while the ultrasonic head applies the ultrasonic vibration. Various methods are disclosed including methods of transferring the solder with or without external heating.
