A dispensing apparatus includes a frame having a gantry configured to provide movement in the X axis and Y axis directions, and first and second dispensing units coupled to the gantry and configured to dispense material onto a substrate. The second dispensing unit is coupled to the gantry by an automatic adjustment mechanism. The dispensing apparatus further includes a controller configured to control the operation of the gantry, the first dispenser, the second dispenser, and the automatic adjustment mechanism. The automatic adjustment mechanism is configured to move the second dispenser in the X axis and Y axis directions to manipulate a spacing between the first dispensing unit and the second dispensing. Methods of dispensing material on the substrate are further disclosed.

A high-density bioprobe array is provided comprising conductive or optical shanks. A method of making high-density bioprobe arrays also is provided. A bioprobe system using the array also is provided.

The present invention discloses a three-dimensional circuit board processing apparatus, including an input module, a vertical processing module, and an output module, which are arranged in sequence. The vertical processing module includes a conveying unit and a processing assembly. A vertical conveying port is arranged on each of two sides of the vertical processing module. The input module is connected to one end of the conveying unit, and the output module is connected to another end of the conveying unit. The input module and/or the output module are/is a flippable module. According to embodiments of the present invention, by arranging the flippable input module and/or output module, the circuit board may enter and exit the vertical processing module vertically, and may be uniformly processed through the vertical processing module, thereby enhancing the processing quality of the circuit board and improving the automation performance of three-dimensional processing.

In order to remove treatment liquid (21) from a planar material to be treated (10), which is transported in an assembly for the electrolytic or wet-chemical treatment of the material to be treated (10), or to promote the exchange of material on the surface of the material to be treated (10), a roll with a roll surface (4, 14) is provided. The roll surface (4, 14) is arranged relative to a transport path of the material to be treated (10) so that a gap (8, 18) remains between the roll surface (4, 14) and a useful region of the material to be treated (10) opposing the roll surface (4, 14), which extends over the useful region. The roll is driven rotatably so that at the gap (8, 18) a relative speed is produced between the roll surface (4, 14) and the material to be treated (10).

The present invention discloses a carrying device, a wet etching apparatus and a usage method thereof. The carrying device comprises a carrying body and a heating unit both disposed under a to-be-processed substrate, the carrying body is used for carrying the to-be-processed substrate such that the to-be-processed substrate is placed inclined; the heating unit is used for heating the to-be-processed substrate, such that temperature of the to-be-processed substrate rises gradually from a top portion to a bottom portion thereof. In the technical solution of the present invention, by disposing the heating unit under the to-be-processed substrate, the temperature of the to-be-processed substrate rises gradually from the top portion to the bottom portion thereof, thus etch rate of the etchant on the bottom portion of the to-be-processed substrate can be increased, and uniformity of etch rate in the inclined wet etching process is improved.

A high-density bioprobe array is provided comprising conductive or optical shanks. A method of making high-density bioprobe arrays also is provided. A bioprobe system using the array also is provided.
