EFD Inc. and Leister USA have collaborated to bust the myth that you cannot perform laser reflow with solder paste. Using Leister diode lasers, EFD has formulated solder pastes that survive the rapid reflow cycle typical of laser heating. These solder pastes reflow and wet well, without spatter, even when heating is accomplished in less than half a second. The flux core in wire solders cannot boast such flux spatter resistance in such an aggressive heating environment.

With the onset of 1900’s, the novelty of printed circuits boards got started with a profound concept of constructing an electrical path on an isolated surface of a board. The initial trend of printed circuit board got into a vain to develop and upgrade the radios and gramophones. Gradually the notion of ‘Through Hole Technique’ came into picture to produce a double sided PCB. In mid 1990’s the idea of auto assembly process was introduced by PCB Manufacturer USA. This was a point of modern touch to enhance the fabrication process with automated soldering technique. The research and development picked up a pace for end to end electronic solutions for defense and US army.

Over the last years more and more international newspapers reported in Europe / USA and Japan: "Tunnel train got stuck under the Channel – thousands of people stranded", "Recall of thousands of cars to workshops for control and repair", "Power Failures left households without energy for hours." Very often news like this relate to malfunctions of electric and electronic circuits under adverse conditions or sometimes even in normal operating environment (...) The presentation will deal with all kinds of aspect of cleaning to ensure the reliability of electronic circuitry in ever changing operation conditions in the most important industrial areas.

A major drawback to Industry 4.0 that few write about is maintenance of an industry 4.0 plant. The maintenance aspect is a much greater and immediate drawback than even the commonly known major concern of security, and the lesser concern of system integration standards. Maintenance of 4.0 systems has, and will continue to result in related huge increases in process downtime. The barriers to overcoming the maintenance/downtime drawbacks of a 4.0 system are almost insurmountable. Has the Smart Manufacturing Leadership Coalition (SMLC) addressed the maintenance paradox? “... model also demands the ability to calculate and manage risk and uncertainty within very different operating structures. ..” Continue reading in pdf or for even more see and share http://bin95.com/Industry40inUSA.htm

The main goal of this paper is to highlight the importance of interrelating the physics and the chemistry in wave soldering and soft soldering in general. Often we find the disciplines of chemistry and physics being analyzed distinct and separate. However in the quest for alternative ways for leading edge competitive and especially environmental friendly manufacturing, separating or ignoring this interrelationship is detrimental to the success of No-Residue soldering.

Recently a large global player approached us with a problem. They needed an initial assembly solution for brand new components. Their boards and CSP specimens could not safely be soldered due to wetting problems at the solder joints.

With the use of laser light for reflow having been established, all that remains is to apply it to best effect. Each time a laser is fired, it pumps a specific amount of energy at a particular wavelength to a particular point in space. Where technique comes in is choosing where and for how long to apply that light along with the application of accessory equipment to optimize solder paste reflow. This presentation covers the specifics of how to determine which process choices are the right process choices based on the needs of your product to maximize yield and throughput.
