Our automated X-Ray inspection systems are able to monitor a variety of aspects of a printed circuit board in assembly production. The inspection is done after the soldering process to monitor defects in soldering quality. Our equipment is able to “see” solder joints that are under packages such as BGA, CSP and FLIP chips where the solder joints are hidden. This allows us to verify that the assembly is done correctly. The defects and other information detected by the inspection system can be quickly analyzed and the process altered to reduce the defects and improve the quality of the final products. In this way not only are actual faults detectd, but the process can be altered to reduce the fault levels on the boards coming through. Use of this equipment allows us to ensure that the highest standards are maintained in our assembly.

Affordable welding fume extraction equipment online shopping UK today: The X-Tractor from Lincoln has a “Mini” in it, which is self-explanatory. The machine isn’t as heavy-duty as most welding fume extractors, but no other device can beat the X-Tractor Mini in terms of portability. The X-Tractor Mini is compact and extremely lightweight. You can just pick it up and set it anywhere you like, from your garage to a store. But, the lighter weight doesn’t compromise efficiency. 2 Different Airflow Settings and 2.4 HP Motor This portable weld fume extractor comes with 2 different settings to choose the preferred airflow. The lower one will generate 95 cubic feet per minute, and the higher one will generate 108 cubic feet of airflow per minute. The amount of airflow seemed a little less to me, but you can’t expect more from a 2.4 HP motor. Besides, the size of the machine speaks for itself that it’s highly portable, which requires a bit of compromising on the power’s end. Explore extra info at fume extraction. A few advices on fume extractors and welding equipment, MIG and TIG welders, plasma cutters. A MIG welder uses a continually feeding spool of thin filler wire as an electrode fed by a wire feed gun to form an electric arc between a wire and the work-piece metal. This heats the work-piece metal and the electrode, causing them to melt and join together to create the weld. Mig welding can be either Gas or Gasless and each have benefits. Gasless welding is far more portable as there’s no gas bottle to carry around, saves cost on having to buy gas bottles and regulators, is easier on positional welds and can penetrate deeper than Gas MIG although the welding wire for a gasless MIG is more expensive than a gasless MIG. Gas MIG welding produces much cleaner welds with no slag or spatter, is slightly better on thinner metals and the welding wire is cheaper than gasless MIG wire.
The smoke extractor is designed to work noiseless because of the brushless fan. Comparing to the rest of the fume extractors referred in the review, Xytronic 426DLX is a top fume extractor, despite its 4.5lb weight. Its weight is not a troubling issue when you want to port to different locations. The activated carbon filters are easy to remove and strong enough to absorb noxious flux and fumes. Its maximum airflow is about 95/115CFM, at average 20-22W power consumption, which is not so powerful, but moderate to industrial standards. However, by using a 130mm2 filter, keeping your soldering work within a foot gives the best fume absorption result. The fume extractor mounted on a solid metal frame, and it delivers the best extraction result and helps to clean your working area free of toxic fumes and smokes.
5 MIG welding machines guides plus MIG welders online store: All welding requires the application of heat, which melts the metal being welded. With the TIG process, the heat comes from an electric arc that streams between the electrode in a hand-held torch and the metal being welded. The arc and molten metal are shielded by an inert gas, which protects the electrode and base metal from oxidizing. Filler rod is usually added to the puddle of molten metal as the weld progresses. The essence of making a good weld is heat control, which is governed by how you modulate the arc as it streams from the torch. Let’s look at this in detail. Explore a few more info at https://www.weldingsuppliesdirect.co.uk/.
High quality online provider to buy span gas bottle in UK: When considering a shielding gas for welding aluminum, we need to consider the differences between argon and argon helium mixtures. In order to understand the effect of these gases on the welding operation, we can examine the properties of each gas in fig 1. We can see immediately that the ionization potential and the thermal conductivity of the helium shielding gas is much higher than that of argon.

Explore additional details on fume extractors. A few advices on welding fume extraction and welding equipment, MIG and TIG welders, plasma cutters. ARC Welding : ARC welding is one of the oldest welding processes around. It uses either an AC or DC power supply to create an electric arc between the welding rod and the workpiece metal to melt the metals and join them together. This style of welding is relatively inexpensive and very portable but it does require some practice to get good consistent welds and the welds will probably require some arc weldercleaning up afterwards. ARC welding is less suited to welding thinner materials but there is a large range of specialist electrodes (welding rods) available for ARC welders depending on what materials you are welding. ARC welding is versatile but more suited to heavier applications.

Top welding guides: Make sure everything is ‘squeaky’ clean. TIG welding is not tolerant of any contaminants. Be sure to clean your base metal with a good degreaser, BEFORE you scrub it with a dedicated wire brush. Do not use the same brush on different kinds of metal. Wipe the filler rod down with degreaser, too. Get comfortable. Whenever possible, I like to be seated when I’m welding. Even in situations where sitting isn’t possible, any little adjustments to my stance or body position that make me more comfortable will have a noticeable effect on the weld.

A few tips on welding fume extraction and welding equipment, MIG and TIG welders, plasma cutters. Welders with a higher power output can work with thicker metals, but higher voltage welders will require special power supply set ups-either generators or appropriate power outlets. A welder with lower voltage in the 100’s will not be able to handle heavy duty jobs, but it can be plugged in and operated from any outlet. Any welder with power over 200 cannot run off a typical power outlet and will naturally cost more to run. In addition, welders will either run an alternating current (AC) that reverses itself at regular intervals or a direct current (DC) that flows in one direction and does not reverse itself. DC offers a steady rate of energy that leads to hotter temperatures and deeper weld penetration. AC welders usually cost less than DC welders, but the available electrodes are far more limited for AC. In fact, DC welders are more costly but remain popular because their higher power offers a wider selection of electrodes and a number of working advantages such as: simple arc striking, better penetration, and improved control. Welders who expect to work on a wide variety of projects may want to consider an AC/DC combination welder.
Many consider price is an important factor for selecting the best fume extractor, and if you are falling one among the category, we recommend 1000l Adjustable Solder Smoke Absorber Remover Fume Extractor Carbon Filter Quiet Fan for ESD Soldering Station as a preferable option.

Best quality welding supplies: Should the electrode accidentally touch the metal or the filler, the electrode often becomes contaminated — meaning some of the rod or base metal gets stuck to it. Once the electrode is contaminated, the arc cone becomes misshapen, making it difficult or impossible to aim the arc with precision, and the boiling contaminants on the electrode may spit out impurities, further compounding your problems. The angle between the torch and the base metal is important, too. You need to angle the torch slightly to see the puddle, and provide access for the filler rod. A 15-degree angle is a good starting place, although some welders prefer a bit more or less. If you hold the torch at 45 degrees (or more), you’re losing a lot of the coverage from shielding gas, and the flatter angle will make the puddle longer than it is wide. For the record, the torch is tipped with the electrode pointing forward, in the direction of motion. Find a few more info at https://www.weldingsuppliesdirect.co.uk/.
Best online shop to purchase calibration gas in UK: In answer to your questions, there are a number of choices available for gases and gas mixtures that can be used to weld aluminum. The choice is usually based on the specific application. Generally speaking, the high helium content gases are used for GMAW welding on thicker materials and GTAW welding with DCEN. Pure argon can be used for both GMAW and GTAW welding and is the most popular of the shielding gases used for aluminum. The helium content gases are usually more expensive. Helium has a lower density than argon and higher flow rates are used when welding with helium. It is possible to increase welding speeds in some circumstances by using helium and/or helium/argon mixtures. Therefore, the extra cost of the helium mixtures may be offset by your improved productivity. You should try the different gas types and choose the one that best suites your specific application.
High quality pcb assembly service provider? Best Technology, establish on June 28, 2006, is a Hong Kong registered company whom focused on one-stop solution provider of FPC, Rigid-flex, MCPCB, FR4 PCB, Ceramic PCB, Special PCB such as Heavy Copper (up to 20 OZ), extra thin PCB (0.10, 0.15mm), and PCB assembly service. Find more details at thin core pcb. A PCB is sort of like a layer cake or lasagna- there are alternating layers of different materials which are laminated together with heat and adhesive such that the result is a single object. The base material, or substrate, is usually fiberglass. Historically, the most common designator for this fiberglass is “FR4”. This solid core gives the PCB its rigidity and thickness. There are also flexible PCBs built on flexible high-temperature plastic (Kapton or the equivalent). You will find many different thickness PCBs; the most common thickness for PCB & MCPCB products is 1.6mm (0.063″). Some of our products- Best Technology boards and Arudino Pro Micro boards- use a 0.8mm thick board.
Double sided flex circuits consists with double sided copper conductors and can be connected from both sides. It allows more complicated circuit designs, more components assembled. The major material used are copper foil, polyimide and coverlay. Adhesiveless stack up is popular for better dimensional stability, high temperature, thinner thickness. Dual access flexible circuit board refer to the flex circuit which can be accessed from both top and bottom side but only has only layer of conductor trace. Copper thickness 1OZ and coverlay 1mil, it similar with 1 layer FPC and opposite side FFC. There’re coverlay openings on both sides of flex circuit so that there’re solderable PAD on both top and bottom sides, that is similar with double sided FPC, but dual access flex circuit board has different stack up because of only one copper trace, so no plating process is need to make plated through hole (PTH) to connect between top and bottom side, and trace layout is much more simple. Quality Policy: PCB Quality is the core of products. All of engineer & vital department guys has more than five years expenrience in PCB industry, we follow up the default PCB standard, as well as with clients’ special request.
Flat Flexible Cable (FFC) is made of PET insulation material and extremely thin tinned flat copper wire, it has free bending and folding, thin thickness, small size, simple connection, easy to solve electromagnetic shielding (EMI). Common ffc cables’ specifications are 0.5mm, 0.8mm, 1.0mm, 1.25mm, 1.27mm, 1.5mm, 2.0mm, 2.54mm and other various pitches to match different types of connectors. Rigid-flex PCB is a circuit board combined of rigid board and flexible circuit, from 2 layer to 50 layers, has the advantage of rigidness, flatness, flexibility and bendability. You can see advantage of rigid flex circuit such as design high density, less components need, less space, and stack up. Welcome to visit Best Technology rigid flex pcb manufacturers.
Despite all the precautions, damage to the Flexible PCB can occur. That is why one should constantly check for faulty components by testing all components to figure out the faulty ones and then replacing them so that the board functions well. Every so often, the issue could be caused by bad soldering. In such cases checking the soldering condition and repairing it works well. While components and soldering failure are easier issues to tackle, you could also be dealing with a complex circuit issue. If the circuit is indeed the problem, the PCB must be returned to the factory for the necessary repair. These are the most probable factors that may have caused your flexible PCB some damage. When you take care of such factors beforehand, you can avoid damages to your PCBs and save time and effort for your organization. To develop sturdy and long-lasting PCBs, it is always recommended to choose a reputed PCB Fabrication company that develops sturdy PCBs for you that have rare chances of getting damaged.
