Abstract:
A method is provided for forming at least one continuous line (104, 106, 108, 110) of viscous material between two components (100, 102) of an electronic assembly forming two substrates (100, 102). The method includes the steps of depositing a plurality of spaced apart dots (20) of the viscous material onto a surface (98) of a first one (100) of the substrates (100,102) and bringing a second one (102) of the substrates (100, 102) into contact with the dots (20) causing the dots (20) to merge together to form at least one continuous line (104, 106, 108, 110) of the viscous material between the two substrates (100, 102).
Abstract:
A non-contact jetting dispenser, viscous fluid dispensing system and method. The system (10) includes a viscous fluid dispenser (12) for dispensing the viscous fluid (20). The system (10) further includes a viscous fluid supply container (26) adapted to hold the viscous fluid (20). A flow path is provided for the viscous fluid (20) between the viscous fluid supply container (26) and an outlet (16) of the viscous fluid dispenser (1 2). An electronic flow meter device (32a, 32b) is used to produce electrical output signals proportional to the flow rate of the fluid flowing through the flow path. A control (40) is operatively coupled to the electronic flow meter (32a, 32b) for continuously receiving and processing the electrical output signals and performing a responsive control function in a closed loop manner.
Abstract:
A fluid dispensing system (30) having first and second applicators (34, 38) includes a primary positioner (36) having a first drive (100a, 100b) that moves the first and second applicators (34, 38) simultaneously along a first axis, a second drive (102) that moves the first a second applicators (34, 38) simultaneously along a second axis, and a third drive (104) that moves the first and second applicators (34, 38) simultaneously along a third axis. A secondary positioner (40, 300) is supported by the primary positioner (36) and has a first drive (106, 316) that positions one of the first or second applicators (34, 38) relative to the other along the first axis, a second drive (107, 328) that positions one of the first or second applicators (34, 38) relative to the other along the second axis, and a third drive (108, 344) that positions one of the first or second applicators (34, 38) relative to the other along the third axis. The third drive (108, 344) of the primary positioner (36) moves the secondary positioner (300) along the third axis.
