SCREEN PRINTING MACHINE
A screen printing machine configured to print solder onto a surface of a circuit board using a screen mask. The screen printing machine is provided with: a screen mask arranged at a top side of the circuit board; a box member arranged at an underside of the circuit board including a space that is closed by the circuit board; a negative pressure generator connected to the space of the box member and configured to create negative pressure inside the space; a sensor configured to detect a pressure inside the space; and a control device configured to control the negative pressure generator based on the pressure detected by the sensor.
Polymer Composition For Laser Direct Structuring
A laser activatable polymer composition is provided. The composition contains at least one laser activatable additive and at least one high naphthenic thermotropic liquid crystalline polymer that contains repeating units derived from naphthenic hydroxycarboxylic and/or dicarboxylic acids in an amount of about 10 mol. % or more. The polymer composition exhibits a dielectric constant of about 5 or less as determined at a frequency of 2 GHz.
PRINTING SCREEN FOR USE IN A METHOD FOR THROUGH-PLATING A PRINTED CIRCUIT BOARD AND USE OF SUCH A PRINTING SCREEN IN SUCH A METHOD
A printing screen for use through-plating a printed circuit board. The printing screen has at least one screen hole for filling a larger hole compared to a reference hole in a ceramic substrate. This printing screen has an area-reducing and area-dividing geometry that divides the screen hole into at least two hole sections.
Component attach on metal woven mesh
Methods of and devices for coupling metal woven mesh or metal woven fabric with IC components to make flexible circuits are disclosed. The flexible circuits can be used to make wearable electronic devices, such as a garment with embedded IC chip.
Polymer composition for laser direct structuring
A laser activatable polymer composition is provided. The composition contains at least one laser activatable additive and at least one high naphthenic thermotropic liquid crystalline polymer that contains repeating units derived from naphthenic hydroxycarboxylic and/or dicarboxylic acids in an amount of about 10 mol. % or more. The polymer composition exhibits a dielectric constant of about 5 or less as determined at a frequency of 2 GHz.
Guided transport path correction
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.
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.
