The component is mounted by device of soldered connection elements on a printed circuit board, and comprises a component casing, and a casing underside turned towards the upper side of the printed circuit board. Metallised or hot glue coated sections (4, 4', 8) are formed as integrated ...
on the edge of the circuit board, along with ESD and circuit protection components. Next, the main functional chips, like microcontrollers, followed by auxiliary components, such as decoupling capacitors, should be placed. Finally, all the passive components, such as resistors, should be mounted....
In the visual inspection for the printed circuit board on which electronic components are mounted, to ensure a good connection of the printed circuit board... 新井 健史,廣安 毅久,渡部 典生 被引量: 0发表: 2013年 Patent Issued for Method for inspecting mounting state of component, printed cir...
PURPOSE:To contrive speeding up of machine-tact, by dividing components to be mounted through a mounting system on the basis of each substrate into a plurality of groups of the components according to each size or weight of the components and mounting them to a plurality of substrates in an ...
Surface-mount devices are mounted directly to a PCB. These SMD components are smaller than the through-hole components and comprise a small lead or no lead at all. Since SMD components require fewer drilled holes, they incorporate higher routing density, and the design becomes more compact. ...
11, a shielding case 9 encloses components mounted on the components side of the printed circuit board (referred to as PCB hereinafter). The shielding case 9 has legs 9a which are inserted through holes 8a into the PCB 8 and soldered to a copper foil pattern 8b by means of solder 11....
Once mounted on a PCB, the component is then considered to be a physical component. It’s worth noting that in most cases, the logical symbol also represents the physical component. When this is the case, the references for each will be the same. However, one exception is that Figure 1...
High-density interconnection (HDI) substrates have high-density circuits that make it possible for electronic parts mounted on a PCB to send and recieve electrical signals between themselves.More... RF PCB As there is no need to use connectors between modules, this substrate is advantageous in te...
The component footprint can also include optional 3D body objects which define the physical space or envelope of the actual component that is mounted on the board. By defining the physical component using 3D body objects or imported STEP models, 3 dimensional component clearance checking can be pe...
Electrical components such as capacitors, diodes, resistors and the like are typically mounted directly to PCBs by connecting the leads of the electrical component to the PCB through soldering and the like. In some circumstances, such mounting is not feasible. In particular, some PCBs are placed ...
