WebFigure 3: SOIC pad layout with ‘solder thieves’ Robber pads are usually two or three times the width of the component pin but the same length, and added beyond the end component pins as in Figure 4. In some cases either edge could be the leading edge of the board in wave soldering, so thieving pads would be provided at both ends.

WebSaid more technically, the mass to solder pad surface area ratio for such devices should be lower than 4.5 gm/cm2. The solder side of a double-sided mixed-tech board may also be soldered by wave solder if the design permits. Using only discrete devices on the solder side and avoiding BGAs and Fine Pitch keeps this option open. WebP Pad Land or solder pad A PCB termination area.

WebA set of board + parts + cable (soldering required) that can output all GPIO of Raspberry Pi model B + to the outside. This is useful for experiments on breadboards. The T-shaped board minimizes the breadboard's occupancy, so it can be used extensively. WebThere are many reasons copper thieving may be added to a PCB. The primary reason is to make the copper distribution across a layer as uniform as possible to make etching and plating more predictable. The etch and plating processes are performed by submerging a copper clad panel into a chemical bath, so areas that have different copper densities ...
WebSolder shorts are common on SOIC devices. If the short is in the middle of the row and the pad width is below 0.022", it is a process problem. Fluxing is the first area to examine, then look at adjustment to the contact time in the wave. Often changing the angle of the conveyor eliminates this defect. Unfortunately many wave soldering systems ...
WebOct 30, 2024 · If the process itself requires a carrier for wave soldering, then a "Solder thief tool" can be designed on the wave soldering carrier to replace the soldering pad on the PCB.
