51.11.1.3.2 Conductor Spacing. Conductor spacing is the distance between adjacent edges (not centerlines) of isolated conductive patterns or features. The spacing between conductors and/or lands is designed to allow sufficient insulation between circuits. A reduction in the spacing can cause electrical leakage or affect the capacitance of the circuit. The crosssectional width of conductors is usually nonuniform. Therefore, the spacing measurement is taken at the closest point between the isolated conductors and/or external annular ring (the portion of conductive material completely surrounding a hole). 51.11.1.3.3 External Annular Ring. The portion of conductive material completely surrounding a hole is called the annular ring (see Fig. 51.7). The primary purpose of the annular ring is that of a flange surrounding the hole; it provides an area for the attachment of electronic component leads or wires and acts as an anchor for the circuit. The minimum annular ring dimension needs to be defined by the PCB user and will differ based upon the function of the ean 8 excel EAN - 8 Barcodes in Excel

program 7-3 holes and whether they are plated or not Annular ring dimensions that are less than those specified can interfere with attachment of the component, and a pad breakout (zero annular ring) condition associated with the area where the circuit enters the pad can reduce the current-carrying capacity of the circuit After verifying the dimensions of the PCB and then verifying that the minimum widths of the annular rings on all other lands are within the procurement documentation requirements, the pattern is found to be in registration with the drilled hole location Front-to-back pattern registration can also be inspected in this manner 5111134 Plating Adhesion A common method of inspecting for plating adhesion is the tape adhesion test, which is described in detail in the IPC test method IPC-TM-650, 241. ean-8 check digit excel Check Digit for 8 digit number - MrExcel.com

The basic test method is performed by adhering tape of known properties onto the plating, rapidly removing the tape, then FIGURE 517 Minimum external annular ring (includes plating) (Courtesy of IPC) inspecting the tape for removed plating on the tape adhesive 5111135 Peel Strength Peel strength is the force per unit width required to peel the conductor or foil from the base material It is usually associated with the acceptance testing of copper-clad base material upon receipt, but it is sometimes used to test the adhesion of the conductors to the finished PCB Peel strength tests of conductors are usually performed after the specimens have been dip or reflow soldered Peel strength tests of conductors are a good method of ensuring that the conductor-to-base material adhesion is sufficient to withstand assembly and rework operations 511114 Hole Characteristics. fuente ean 8 excel Calcolo check digit EAN13- EAN8 con Excel | Maurizio Condini ...

PTHs provide circuit interconnection from the surface of the PCB to internal layers and to circuitry on the opposite side For this reason, much attention is correctly focused on the acceptability and quality of these holes Nonconformance in the PTHs is a serious concern 5111141 Roughness and Nodulation Roughness is an irregularity in the side wall of a hole; nodulation is a small knot or an irregular lump found in or on the plating Although roughness and nodulation are not desirable, they are allowable in small amounts Roughness and nodulation create one or more of the following nonconforming conditions:. Reduced hole diameter Impaired lead insertion Impaired solder flow through the hole Voids in solder fillet 51.11.1.4.2 Voids in the Plating and Finished Coating. A void is the absence of material where it is intended to be. Copper-plating voids are evaluated again during microsectional analysis, but this sampling is very small and this attribute should be thoroughly evaluated during visual inspection of the PCB. When visually evaluating voids in the PTH copper, no more than 5 percent of the holes on the PCB should exhibit evidence of voids. In holes that have voids (see Fig. 51.8), there should be no more than one void that is less than 5 percent of the hole length. Voids in the finish coating of the PCB (see Fig. 51.9) that do not extend to the copper plating are allowed in larger quantities than voids in the copper plating. There should again be surface finish voids in no more than 5 percent of the PCB holes, and these holes should have no more than three voids that are each less than 5 percent of the hole length. You may find that your page contains a UI component that, on reflection, you think would better be represented by a different UI component. Rather than deleting that UI component and then replacing it with a different component and having to rebind the new component, JDeveloper allows you to convert from one type of UI component to another.
