• FAQ - frequently asked questions1 What is ICT & FCT test? The in-circuit test (ICT) involves the measurement of all individual ingredients of an assembly Defective elements are detected and may get replaced if needed The function examine (FCT) checks an meeting purposes 100 percent as supposed The trying out surroundings simulates the supposed subject of utility and the electric behaviour of the assembly is examined A multitude of alternative test probes are available in for the optimal fulfilment of the contacting assignment These fluctuate in set up height, grid size (possible distance between probes), tip style, and connection kind The electrical connection is often made via a solder cup, a wire-wrap post, as well as with or without cable 2 What is PCB ? PCB (Printed Circuit Board), also referred to as DUT, PCB or meeting The PCB is equipped with electronic components and can be present in practically every digital device In order to ascertain whether the person elements are placed within the right place or operate correctly, the PCB must veritably be tested earlier than use or set up three How to make your mind up tip kind of probes ? The number of appropriate tip style is one of the main points in selecting the correct verify probe Many of the tip types can be used for a number of purposes A classic classification can be made with appreciate to the geometry of the verify points, reminiscent of pad, via, pin or posts Furthermore, the examine point could be differentiated by its size and surface situation (oxidised, clean or contaminated via residue from the soldering process) Depending on the DUT and verify conditions, it can be necessary to attempt several tips styles and spring forces to be able to find an optimal combination four What is set up height? The set up height is the space between the probe tip of the verify probe in the home role (unloaded) and the probe plate The installation top relies on the receptacle Depending on whether or not check pads or factor pins are contacted, diversified strokes happen throughout contacting In critical cases, adjusting the installation top accordingly is usually recommended five What is Grid? The time period grid describes the space between two verify points on a broadcast circuit board (PCB) or gadget beneath check (DUT), or the gap between two element pins or connectors Based at the examine probe, the space is defined as the centre of one mounting hole to the centre of subsequent mounting gap on the probe plate There are the world over recognised grid distances which brands of PCBs and connectors notice As the definition is based on imperial models instead of metric units, the grid size is given in inches The grid sizes are often very small so the grid size 1/1000 inch is used 1/1000 inch is also denoted as Mil The commonest grid sizes are: forty Mil = 1 mm 50 Mil = 1 mm seventy five Mil = 1 mm one hundred Mil = 2 mm Note 1 Please enable 0-1mm error thanks to handbook measurement, please confirm that you simply know and accept the mistake before purchasing 2 Due to the difference between diversified monitors, the picture may not mirror the actual coloration of the item,please make sure you don't mind before ordering three When order goods transport to U territiries or overseas destinations,there may perhaps price further specific shipping fees In addition, When order items are despatched from us for your country, there could have a series of related costs reminiscent of breakage fees, extra express delivery costs and the import tax on your nation However,our delivery cost would not consist of any additional customs expenses and buyers are liable for customs duties These extra charges may be gathered at time of delivery We will not refund shipping fees for refused shipments About delivery · Normal transport approach : Buydo Standard Shipping, Buydo Saver shipping，Cainiao Standard For Special Goods，Cainiao Super Economy Global，Cainiao Super Economy ，Cainiao Super Economy For Special Goods · Fast shipping way: DHL , Fedex and UPS, if you would like other Express, please message us · All orders may be despatched with legitimate monitoring number · If you prefer to know more information about products,pls don&;t hesitate to ask us, we are able to examine and reply your message ASAP About refund& feedback - If you should get refund , pls be at liberty to touch us first, we can do all our greatest to solve the issues for you - If you are satisfied with our products and service, pls go away fantastic feedback with an overall Detailed Selling Rate of 5-Star Thank you !
