A circuit board includes a substrate, a plurality of contacts disposed on a surface of the substrate, and a solder mask. The contacts have a plurality of plating regions and a metal layer on the plating regions, and the plating regions have at least two different sizes. The solder mask covers the surface of the substrate and covers edges of the plating regions, in which topmost surfaces of the contacts are below a top surface of the solder mask, and a gap between the topmost surfaces of the contacts and the top surface of the solder mask is larger than 0 &#x3bc;m and is smaller than 5 &#x3bc;m.

Circuit board

A method of fabricating a circuit board includes forming a conductive layer on a surface of a substrate, and patterning the conductive layer to define a plurality of plating regions and a plurality of plating lines. The plating regions have at least two different sizes, a first group of the plating regions are interconnected by a first plating line of the plating lines, and a second group of the plating regions are interconnected by a second plating line of the plating lines. A ratio of a total area of the first group of the plating regions to a total area of the second group of the plating regions is from about 1 to about 5. A solder mask is formed on the surface of the substrate to cover the plating lines and partially expose the plating regions. At least one metal layer is electroplated on the exposed plating regions.

An adjusting mechanism for the lens set of an imaging system, which is applied to digital photo-taking system, monitoring system, and the like for precisely adjusting the lens set thereon, comprising a pivoting means located inside the imaging system for providing rotation capability to the lens set having the rotation center located at the pivoting means and close to the anchoring end of the lens set; a driving means, located inside the imaging system, for driving the lens set to rotate around the pivoting means; and a human-machine interface for facilitating the operator to control the driving means indirectly.

Adjusting mechanism for the lens set of an imaging system

A device for controlling a rotation of a lens in a digital camera includes a lens connected to and exposed out of the housing of a digital camera and a motor disposed within the housing of the digital camera. The lens is provided with a shaft which extends through the housing to have an end extending into the interior of the housing which is disposed with a follower gear. The motor has a drive spindle which is disposed with a driving gear. A set of reduction gears are disposed between and engageable with the follower gear on the shaft of the lens and the driving gear on the drive spindle of the motor. By means of the rotation of the motor, the lens is rotatable horizontally, while the digital camera remains stationary, to a desired direction in order to take a picture.

An aperture selection mechanism for camera lens includes an aperture strip and a disk selection knob. The aperture strip has two or more different sizes of apertures equally spaced from each other and being sequenced by size. Turning the selection knob, the aperture strip will be moved and one of the apertures will be positioned in the light path of the camera lens. Two or more apertures may be moved to the light path of camera lens one at a time so that the camera can produce better quality of photo and image. The structure is simple, low cost and easy to use.

Aperture selection mechanism for camera

A lens movement mechanism for digital camera includes a lens set which has a composite lens and a Charged Couple Device built therein, a first movement member for turning the lens set angularly left or right, and a second movement member for turning the lens set angularly up or down. The first movement member includes a bracket piovtly holding the lens set and a gear set for turning the bracket and the lens set left or right angularly. The second movement member includes a slant block with a slope surface contact with a rear end of the lens set so that when the slant block is moved transversely, the lens set will be tilted up or down angularly. Therefore the lens set may be turned left or right, up or down smoothly and precisely without a user's hand moving the lens set directly. The lens may be prevented from hand smearing. Higher photo quality may be achieved.

A moveable lens apparatus for digital camera includes a CCD lens set, a first motion mechanism having a bracket pivotally holding the lens set and a first gear set for driving the bracket and the lens set to rotate left or right angularly, and a second motion mechanism having a guide slidably engageable with a rear end of the lens set, a gear rack vertically attached to the guide and a second gear set for driving the gear rack and the guide up or down so that the lens set may be swung pivotally up or down. The first and second gear set may be actuated manually or by motors. The lens set thus may be moved and rotated smoothly and precisely without a user's hand directly touching the lens set.

Moveable lens apparatus for digital camera

An extended adjusting mechanism for the lens set of an imaging system, which utilizes motion connection means between the main body and the lens set of the imaging system to enlarge the view scope of the imaging system, comprises the lens set for viewing and recording and a connection carrier located at one side of the main body. The connection carrier, which is a carrier for the lens set, further comprises a base connected rotationally to the main body and a dumb-bell connection as a motion junction means between the base and the lens set.
