Two-step, direct-write laser metallization
A method for manufacturing includes coating a substrate (22) with a matrix (28) containing a material to be patterned on the substrate. A pattern (42) is fixed in the matrix by directing an energy beam to impinge on the coated substrate so as to fix the pattern in the matrix without fully sintering the pattern. The matrix remaining on the substrate outside the fixed pattern is removed, and after removing the matrix, the material in the pattern is sintered.
Electronic device
An electronic device comprises a metal casing, a circuit board and a heating assembly. The metal casing has a storage space. The circuit board is located in the storage space. The heating assembly comprises a first heating part and a second heating part. The first heating part is in thermal contact with the circuit board, and the second heating part is in thermal contact with the metal casing.
Fog Bonding Device and Method Thereof
A bonding device and bonding method for bonding an FPC film on a display panel through an anisotropic conductor attached to the display panel, the device including a panel supporting unit configured to support the display panel; a heating and pressurizing unit disposed on an upper area of the panel supporting unit and configured to pressurize and heat a compression area of the FPC film placed on an upper part of the anisotropic conductor towards the display panel, a film supporting unit disposed adjacent the panel supporting unit and configured to support the FPC film, and a film pre-heating unit provided in the film supporting unit and configured to pre-heat the FPC film.
Method for Soldering an Electronic Component to a Circuit Board by Jetting Liquefied Solder into a Through Hole
A method for soldering an electronic component to a circuit board involves jetting liquefied solder. A laser beam melts a solid solder ball to produce a liquefied solder ball before the ball is jetted. The liquefied solder ball is jetted towards a through hole in the circuit board such that a portion of the liquefied solder ball flows into an annular gap between a pin and sides of the through hole. The pin is attached to the electronic component and passes through the through hole. As the liquefied solder ball is jetted towards the through hole, the laser beam is directed at the ball so as to keep it liquefied. How much of the solder ball remains outside the through hole after liquefied solder has flowed into the annular gap is determined. The filling degree of the annular gap is determined based on how much solder remains outside the hole.

Method and arrangement for attaching a chip to a printed conductive surface
A chip attached to and electrically connected with a printed conductive surface, whereby the chip is heated to a temperature, which is lower than what the chip can stand without being damaged by the heat, the heated chip is then pressed against the printed conductive surface with a pressing force, whereby a combination of said temperature and said pressing force is sufficient to at least partly melt the material of at least one of the printed conductive surface, the contact point on the chip, or both, thereby attaching and electrically connecting the chip to the printed conductive surface.
Embedded component package structure and manufacturing method thereof
A manufacturing method of an embedded component package structure includes the following steps: providing a carrier and forming a semi-cured first dielectric layer on the carrier, the semi-cured first dielectric layer having a first surface; providing a component on the semi-cured first dielectric layer, and respectively providing heat energies from a top and a bottom of the component to cure the semi-cured first dielectric layer; forming a second dielectric layer on the first dielectric layer to cover the component; and forming a patterned circuit layer on the second dielectric layer, the patterned circuit layer being electrically connected to the component.
