Method and system for depositing an object onto a wiring board

摘要

A method of depositing one or more stiffener onto a wiring board includes the steps of engaging the wiring board onto a heat-retaining pallet to form an assembly, pre-heating the assembly to a temperature ranged from 70 to 140° C., and disposing the stiffeners onto the pre-heated wiring board of the assembly, wherein the pallet of the assembly retains sufficient heat for the wiring board to at least partially melt the stiffener, more preferably adhesive stiffener, to fix onto the wiring board upon disposition of the stiffeners.

主权项

1. A system, comprising:
a control panel providing an interface for a user to configure the system; a heat-retaining pallet; a wiring board engaged onto the heat-retaining pallet to form an assembly; a pre-heating chamber configured to pre-heat the assembly to a temperature in the range of 70 to 140° C. a conveyor delivering the assembly from the pre-heating chamber to an operating section, wherein the operating section includes one or more robotic arms equipped with a nozzle to pick and place an object onto the wiring board using a suction force; an automated machine; and a stiffener to be deposited onto the wiring board of the assembly by the automated machine; wherein the stiffener has a lower melting point or softening point relative to the wiring board and is coated with a layer of heat-activated adhesive, wherein the heat-retaining pallet is configured to retain sufficient heat to activate the heat-activated adhesive so as to adhere the stiffener onto the wiring board and permit the stiffener to partially melt onto the wiring board.
