Abstract:
The present invention comprises an application step of applying a sealing agent 7 onto one of two substrates 3 and 4 in the form of a frame having corner portions, a dropping step of dropping a liquid material onto one of the two substrates with a predetermined arrangement pattern and dropping the liquid material only to corner portions of a peripheral portion deviating from the arrangement pattern in an area surrounded by the sealing agent, and a bonding step of bonding the two substrates to each other in a reduced pressure atmosphere.
Abstract:
An electronic component holding head, an electronic component mounting apparatus using same, and a method for mounting an electronic component, are provided for use in mounting an electronic component having a positioning mark formed on a film member. The electronic component holding head has a main electronic component holding unit, a vacuum chucking part facing the surface of the electronic component to be held by vacuum chucking so as to hold the electronic component, and a light path for guiding light shined onto a positioning mark formed at an edge part of the electronic component for the purpose of correcting a position offset between the electronic component and the substrate to which the electronic component is to be mounted, the vacuum chucking part holding the electronic component at a position which is on a straight line substantially parallel to an edge of the electronic component and substantially mutually orthogonal over the positioning mark of the electronic component, and which avoids the positioning mark.
Abstract:
An elongation amount of electronic parts to be bonded onto a substrate by thermocompression is accurately controlled, and thereby poor connection of the electronic parts is prevented. An electronic part compression bonding apparatus according to the present invention includes a compression bonding unit (41) which bonds the electronic parts onto the substrate by thermocompression, a pressure supply unit (48), a pressure control unit (83) which controls pressure, a heating unit (43) which heats the compression bonding unit (41), a temperature control unit (85), and a thermocompression bonding control unit (80) which controls the pressure control unit (83) and the heating unit (43) based on thermocompression bonding condition data in which at least one of pressure and heating temperature is variably set during a process from start until completion of a thermocompression bonding operation of the electronic parts. In the thermocompression bonding condition data, the pressure is set to be first pressure in a first stage in a process of the thermocompression bonding operation and second pressure, which is lower than the first pressure, in a second stage that follows the first stag

There is disclosed a method including an applying step of applying a sealing agent onto either one of two substrates, a dropping step of dropping a predetermined amount of a liquid crystal onto either one of the two substrates, a leaving step of leaving the substrate on which the liquid crystal has been dropped to stand under a reduced pressure atmosphere for a predetermined time, and a bonding step of bonding the two substrates onto each other under the reduced pressure atmosphere, after leaving the substrate on which the liquid crystal has been dropped under the reduced pressure atmosphere for the predetermined time.
Abstract:
There is disclosed a method comprising bonding two substrates to each other by a sealing agent, obtaining a positional shift amount between the bonded two substrates, and moving at least one of the two substrates by a correction movement amount obtained by multiplying the positional shift amount by a correction coefficient larger than 1 to correct the positional shift amount between these two substrates.
Abstract:
A liquid crystal dropping apparatus is capable of achieving a high-speed liquid crystal dropping operation and of improving the productivity. The liquid crystal dropping apparatus 10 includes a container 40 for containing a liquid crystal L, a liquid crystal dispensing device 20 for dropping the liquid crystal L contained in the container 40 on a substrate 1, and a stage-moving device 12 for moving the substrate 1 relative to the liquid crystal dispensing device 20. The liquid crystal dispensing device 20 includes a sucking means (suction port 21 and such) for taking out from the container 40 a quantity of the liquid crystal L corresponding to a quantity of the liquid crystal L to be dropped, a temporary storage means (storage chambers 22) for temporarily storing the liquid crystal L taken out from the container 40, and a discharge means (discharge port 23 and such) for discharging the temporarily stored liquid crystal L.
Abstract:
At least when an upper glass substrate 3 held by an upper retention head 10 and a lower glass substrate 4 held by a lower retention head 11 are abutted on each other through a sealing material 5, air cylinders 25, 25 apply a lifting force balancing with a dead weight of the upper retention head 10 to the upper retention head 10 to cancel its dead weight. In this state, the upper glass substrate 3 and the lower glass substrate 4 are abutted on each other through the sealing material 5.
Abstract:
A substrate laminating apparatus has an upper stage for holding an upper glass substrate and a lower stage for holding a lower glass substrate, and which laminates together the upper glass substrate and the lower glass substrate in a condition that both of the substrates are positioned relative to each other. An image pickup device photographs position detecting marks on the upper and lower glass substrates, and a moving device changes a relative distance between the image pickup device and the upper/lower glass substrates. A data acquiring device acquires data about the relative distance between the upper/lower glass substrates and the image pickup device, and a control device controls the moving device based on data about the relative distance.
