Formation of an intermetallic layer at the solder interface indicates good metallurgical bonding, but thick intermetallic layers are undesirable because intermetallics are brittle and prone to fracture, especially if the joint is stressed in tension rather than shear Because solder joint fatigue takes place in the solder rather than in the intermetallics or at the solder/intermetallic interface, the basic mechanism is unaffected Nonetheless long reflow times and the accompanying thick intermetallic layers should be avoided Cross-sectioning can be used to judge the extent of intermetallic growth; as long as the intermetallic layer thickness is relatively small compared to the joint thickness, reliability should not be adversely affected30 (Note however that minimizing reflow time is still a good thing; the reliability of all the components on the board is adversely affected by time at elevated temperature, both during processing and in service. java pdf417 parser keywords: pdf417 - npm search

ZXing ("Zebra Crossing") barcode scanning library for Java , Android - zxing/zxing . FIGure 14-1. Label and icons for buttons access key to the button. In Figure 14-1, P and N are access keys for the Previous and Next buttons. For a Toolbar Button component, you can define Text, Icon, HoverIcon, DepressedIcon, and DisabledIcon, as shown in Figure 14-1, where the icons represent adding, editing, and deleting a customer. TIp When you define icons for your buttons, JDeveloper prompts you to copy each icon into the project. However, if you import all your icons into your project, you can select the icons from a drop-down list instead of manually selecting and importing each icon. Select File | Import and then select Web Source. You can now import all the required icons into the ViewController project. pdf417 barcode javascript Barcode Scanner JavaScript API | Dynamsoft

Unfortunately, in developing a reflow profile, there is often a tradeoff between reflow time and peak temperature) Cleanliness Issues An improper reflow profile can also cause solder balling and increase the amount of flux residue remaining on the board after reflow The reliability concerns associated with these process issues are discussed in Sec 57424 Solder balls can be caused by a combination of improper paste storage or handling, incompatibility between the flux and reflow atmosphere, and a reflow profile that does not conform to the manufacturer s specification 57423 Wave-Soldering Process Improper wave-soldering practice can cause reliability problems The root cause is generally thermal shock, overheating of the top side of the board, or contamination of the solder bath Component Cracking Ceramic components such as resistors and capacitors will crack under thermal shock conditions. When they are located on the bottom of the board they can be heated rapidly by the solder wave Prevention is relatively simple; the assembly must be preheated before it hits the solder wave A temperature difference between the component and the solder wave of less than 100 C is recommended; a typical preheat temperature is 150 C.. pdf417 scanner javascript 6 best open source pdf417 projects.

The stray capacitance (usually a positive charge) of your body provides enough current to switch the line to a high condition as you approach it For us, this means that all input lines have to be tied high or low, with a high resistance when we use them as inputs (or defined as outputs and then made high or low) If you are going to pull the line low in your circuit to read it, tie it high with a 1 meg resistor, and if you are going to pull the line high to read it, tie it to ground with a 1 meg resistor Keeping all this in mind, Figure 15-1 shows the circuit for reading a line that is connected to a switch that grounds it.. FIGURE 7.19 Expanded Teflon (left) and a PCB cross section showing prepreg using expanded Teflon (right). (Courtesy of W.L. Gore and Associates.) A resin system is applied to the expanded Teflon structure and is made into a b-staged sheet capable of bonding printed circuit layers together.This material can be used to make prepregs for high-frequency applications and is shown in Fig. 7.19. The primary conductive material used in printed circuits is copper foil. However, the trend toward circuit densification has brought about recent developments in copper foil technology as well. In addition, copper foils subsequently plated with other metal alloys are employed to manufacture printed circuits with resistive components buried within a multilayer structure. Copper foil grades are shown in Table 7.7.
