Method of dispensing material on a substrate with a solenoid valve of a pneumatically-driven dispensing unit
10071393 · 2018-09-11 · ·

A method of controlling a dispensing unit is used to dispense material on a substrate. The method includes connecting a solenoid coil of a pneumatically-driven pump to an amplifier output of a dispensing system, and driving the solenoid coil with the amplifier to a cause the pneumatically-driven pump to dispense material on a substrate. The method further may include commanding an idle current to flow in the solenoid coil during periods of inactivity. The idle current may be sufficient to cause warming of the solenoid coil, yet not sufficient to activate the solenoid to an engaged position. The method further may include commanding a first current level to flow in the solenoid coil to rapidly activate the solenoid, and commanding a second current level to flow in the solenoid coil after the solenoid is activated.

Transport Path Correction Techniques and Related Systems, Methods and Devices

A printer deposits material onto a substrate as part of a manufacturing process for an electronic product. At least one mechanical component experiences mechanical error, which is mitigated using transducers that equalize position of a transported thing, e.g., to provide an ideal conveyance path; a substrate conveyance system and/or a printhead conveyance system can each use transducers in this manner to improve precise droplet placement. In one embodiment, errors are measured in advance, with corrections being played back during production runs to mitigate repeatable transport path error. In a still more detailed embodiment, the transducers can be predicated on voice coils, which cooperate with a floatation table and floating, mechanical pivot assembly to provide frictionless, but mechanically-supported error correction.

A heat dissipator having a circuit formed by screen printing or spraying includes a circuit layer and an isolation layer. The circuit layer, which is on a surface of a heat dissipation part of the heat dissipator having the circuit formed by screen printing or spraying, is formed by screen printing or spraying a uniformly distributed plastic material and low electrical resistance conductive powder. The isolation layer is disposed on the circuit layer and the heat dissipation part.

GUIDED TRANSPORT PATH CORRECTION
20180160550 · 2018-06-07 ·

A printer deposits material onto a substrate as part of a manufacturing process for an electronic product; at least one transported component experiences error, which affects the deposition. This error is mitigated using transducers that equalize position of the component, e.g., to provide an ideal conveyance path, thereby permitting precise droplet placement notwithstanding the error. In one embodiment, an optical guide (e.g., using a laser) is used to define a desired path; sensors mounted to the component dynamically detect deviation from this path, with this deviation then being used to drive the transducers to immediately counteract the deviation. This error correction scheme can be applied to correct for more than type of transport error, for example, to correct for error in a substrate transport path, a printhead transport path and/or split-axis transport non-orthogonality.

Viscous Material Noncontact Jetting System

A viscous material noncontact jetting system has a jetting dispenser mounted for relative motion with respect to a surface. A control is operable to cause the jetting dispenser to jet a viscous material droplet that is applied to the surface as a viscous material dot. A device, such as a camera or weigh scale, is connected to the control and provides a feedback signal representing a size-related physical characteristic of the dot applied to the surface. The size-related physical characteristics of subsequently applied dots are controlled by heating and cooling, or adjusting a piston stroke in the jetting dispenser, in response to the size-related physical characteristic feedback. Dispensed material volume control and velocity offset compensation are also provided.
