Abstract
The disclosure relates to assemblies and methods for preheating objects in the process of underfill. Specifically, the disclosure relates to assemblies and methods for treating printed circuit boards (PCBs), integrated circuits (ICs) wafers and the like, in the preheating stage of the underfill process using an assembly operable to create a customizable hot-air bath with adjustable depth to account for surface topology and necessary clearances, for soaking the PCBs, ICs, wafers and the like in hot air, bringing these to operating temperature.

(canceled)
An assembly for heating an object, the assembly comprising:
- a) a stage defining a longitudinal axis;
- b) a vertically adjustable platform coupled to the stage;
- and
- c) an adjustable quadrilateral frame, in fluid communication with at least one hot gas blower, the adjustable quadrilateral frame operable for selectably adjusting the dimensions of a closed quadrilateral chamber formed by the quadrilateral open frame, the object forming a lid and a slab coupled to the vertically adjustable platform forming a floor, wherein the object is:
- a printed circuit boards (PCBs), an integrated circuits (ICs), an advanced packaging (AP), a wafer, or an electronic component comprising one or more of the foregoing sought to be heated in a dispensing process.
An assembly for heating an object, the assembly comprising:
- a) a stage defining a longitudinal axis;
- b) a vertically adjustable platform coupled to the stage;
- and
- c) an adjustable quadrilateral frame, in fluid communication with at least one hot gas blower, the adjustable quadrilateral frame operable for selectably adjusting the dimensions of a closed quadrilateral chamber formed by the quadrilateral open frame, the object forming a lid and a slab coupled to the vertically adjustable platform forming a floor, wherein the vertically adjustable platform comprises:
- d) a base plate having a top surface
- e) a motor, coupled to the top surface of the base plate;
- and
- f) a drivetrain operably coupled to the motor, or to an actuator wherein the drivetrain is further coupled to the slab, the drivetrain operable to selectably raise and lower the slab.
A method of heating an object sought to be heated in a dispensing process, the method implemented in an assembly comprising:
- a stage defining a longitudinal axis;
- a vertically adjustable platform coupled to the stage;
- and an adjustable quadrilateral frame, in fluid communication with at least one hot gas blower, the adjustable quadrilateral frame operable for selectably adjusting the dimensions of a closed quadrilateral chamber formed by the adjustable quadrilateral frame, the object forming a lid of the chamber, and a slab coupled to the vertically adjustable platform forming the floor of the closed quadrilateral chamber, the method comprising:
- a) based on the length and width of the object-adjusting the dimensions of the adjustable open quadrilateral frame;
- b) based on at least one of:
- a thickness, topology, and a clearance requirement of the object sought to be heated in a dispensing process, and using the vertically adjustable platform, raising the object through the open quadrilateral frame forming a lid to the closed quadrilateral chamber;
- c) actuating the hot gas blower;
- and
- d) using a sensor included with the assembly, continuously monitoring the temperature of the object for a predetermined time at a predetermined temperature range.
