Component Bake-Out Components that have been sitting out may be subject to water absorption. When components are heated during rework, where the heating cycle is more localized and perhaps more extreme than in the slow heating experienced during mass oven reflow soldering, moistureinduced popcorning may be a more serious problem. Follow IPC or component manufacturer recommendations for presoldering moisture bake-out. Refer to Sec. 50.2.2.5 for further discussion on this topic. code 39 c# class Code 39 C# Control - Code 39 barcode generator with free C# sample

All Code 39 barcode settings below are adjustable. BarCode code39 = new BarCode (); Gold Finger Protection There is ample opportunity to ruin gold edge connector fingers on a circuit board during the repair operation. Care should be taken to keep both solder and flux away from gold fingers during repair. Mechanical shields or acrylic-adhesive polyimide tape can be used to protect fingers from smeared solder paste, loose solder debris, or flux. If solder comes into contact with gold, the gold will rapidly dissolve into the solder mass and the solder will spread on the finger. The solder cannot be removed from the gold finger without scraping and replating, a costly process. Solder is not a reliable connector contact material, especially with today s highdensity, low normal-force electrical connectors. Keep solder away from gold fingers. Keep gold finger temperature as low as possible. Ensure that gold fingers are never handled, even with gloved hands. Avoid lint and fibers. After rework, clean gold fingers with a suitable solvent. Use a soft brush, lint-free cloth, or other nonabrasive material for this cleaning. Clean gold fingers on each side of the board separately. Avoid folding the lint-free cloth over both edges and wiping repeatedly; the cloth will wear against the glass-epoxy expunge and shred, leaving lint on the board. A better alternative is to use a soft, ESD-safe brush with solvent to clean the gold fingers and follow with a filtered-air blow-off to dry. Avoid any materials that will scratch the gold surface finish on the fingers. The underlying nickel, if exposed to the atmosphere will oxidize and, is known to be problematic for separable contact reliability. generate code 39 barcode using c# Code39 Barcode Control For Windows Applications sample in C# ...

IPC/JEDEC J-STD-033, Standard for Handling, Packing, Shipping and Use of Moisture/Reflow Sensitive Surface Mount Devices. Electronic connectors are attached to printed circuit boards in four ways (see Fig. 49.1): Oven reflow surface-mount technology (SMT) soldering Wave soldering (for solder-tail components) Pressure interconnect, a solderless method relying on mechanical forces to hold interconnect elements together to make contact Press-fit, another mechanical, solderless method (which is the subject of this chapter) barcode code 39 c# Code39 Barcodes in VB.NET and C# - CodeProject

Keepdynamic.com provides Code - 39 C# .NET Barcode Generator Library for the creation/generation of Code 39 barcodes in your C# .NET framework projects. Code 39 is an alphanumeric, discrete, and variable-length barcode symbology. In code 39 barcode image symbol, a fixed pattern of bars represents a character. Press-fit, also referred to as press-pin, compliant-pin, and a number of other trade names, has been in use for many years and is a proven and reliable interconnect method. Once used exclusively for passive backplanes, more recently press-fit connectors have gained in popularity and are commonly incorporated on complex motherboards and daughter-cards. Just as circuit boards have become more complex (with thicker, higher layer counts, densely routed circuit traces, and high component counts), so too have pressfit connectors. They are available with high pin density (pin pitch down to 1 mm) and pin counts in the thousands per connector and even strip-line shielding for enhanced highspeed signal performance. Press-fit connectors can be applied to either or both sides of a PCA and are repairable, although first-pass assembly yields are always near 100 percent. Press-fit is easier and more reliable than soldering and does not subject the printed circuit assembly (PCA) to additional thermal or chemical processes an advantage for reliability, and especially advantageous for today s dense circuitry. Since it requires very little energy (no soldering), minimizes materials (no solder), and calls for no chemicals for its application, it is environmentally beneficial. The press-fit process is simple in theory and generally so in practice, relying on oversized connector leads forced into in plated through-holes in the PWB. The plated through-holes in the PWB are sized specifically for the press-fit connector to be applied. As the connector pin is forced into the board, there is slight deformation to the press-fit pin and to the PTH barrel. The result is a mechanically stable, electrical contact. FIGURE 49.1 Four methods of connector attach to printed wiring boards (PWBs): (a) SMT applied by reflow soldering; (b) plated through-hole (PTH) solder-tails that are wave-soldered; (c) pressure-interconnect, which relies on mechanical forces for electrical contact; and (d) press-fit, which relies on mechanical deformation of the connector lead and PTH barrel to make intimate electrical contact.
