摘要： A printed circuit board providing RF shielding. An electrically insulating material serves as a substrate (10) with two opposed sides. At least one side of the substrate (10) has an electrically conductive layer (12) formed in a pattern that defines a printed circuit. An insulating dielectric layer (14) covers at least a portion of the printed circuitry, leaving at least one portion (16) of the circuitry exposed. A radio frequency (RF) shielding layer (18) is formed by depositing an electrically conductive polymer on at least a portion of the insulating dielectric layer. The RF shielding layer (18) also lies over a portion of the exposed electrical circuitry (16), providing electrical connection to the electrically conductive layer (12). The RF shielding layer (18) is formed from a silverfilled polymer thick film ink and is applied by screen printing, stencilling, roller coating, spraying, or other equivalent methods.

摘要： A mounting pad arrangement (FIG. 5) improves reliability of placement of a surface mount component. A first pad array is disposed throughout an area on the surface (308) of a substrate (202), the area having four outside corners. The first pad array includes contact pads (502) arranged in a first linear grid pattern, and eight aligning pads (504,506,510,514,518), larger than the contact pads (502). Two aligning pads (504,506,510,514,518) are near each of the four outside corners. Each aligning pad (504,506,510,514,518) is positioned off center with respect to the first linear grid pattern such that a tangential line (608,610,612,614) can be drawn between an innermost point of the aligning pad (504,506,510,514,518) and corresponding innermost points of the contact pads (502) that are collinear on the first linear grid pattern. A second pad array (406) is disposed on the surface mount component and arranged in a second linear grid pattern that aligns with the first linear grid pattern. Eight pads of the second pad array (406) also align with points of intersection of the first linear grid pattern that fall within each of the eight aligning pads (504,506,510,514,518). Each pad of the second pad array (406) is equal in size to any other pad of the second pad array (406). Solder (312) is disposed between and contacting each pad of the first and second pad arrays.

摘要： A method and an apparatus align and attach a leadless surface mount component (402) including a termination at each end of the component (402). The termination has bottom (704) and end (702) portions for attaching to a corresponding pad on a substrate (102) by a reflow solder process (1200). A pad arrangement (100) is formed including two opposite pads (108), each pad (108) occupying a tri-oval-shaped area. The tri-oval-shaped area includes an elliptical area (110) substantially centered under the bottom portion (704) of the corresponding termination of the component (402) when the component (402) is aligned with the pad arrangement (100), and an arcuate area (112) contiguous with the elliptical area (110) and extending towards the opposite pad (108) in a central lengthwise direction. A solder paste (202) is applied to the elliptical area (110), and thereafter reflowed, whereby solder (302) in the solder paste (202) liquefies and flows onto the arcuate area (112), thereby facilitating alignment of the component (402) with the pad arrangement (100).

摘要： A method for controlling the mass of solder applied to a printed circuit substrate (202) by a solder printer (200), whereby the mass of solder paste (114) applied to a printed circuit substrate (202) is controlled by measuring the mass of the solder paste (114) that was applied to a first printed circuit substrate. The mass data measured is then compared to a predetermined mass to produce a control signal. The mass of the solder applied to a second printed circuit substrate is controlled as a function of the control signal so that the mass of the solder applied to the second substrate more closely approaches the predetermined mass.
