Profile: Challenge Electronics specializes in all aspects of electronics design, electronics manufacture, and product assembly. We are certified with ISO 9001:2000 certification. We also deal with manufacture of electronic PCBs, sub-assemblies, and finished products. Our work includes design and manufacture of industrial and domestic heating controls, lighting controls, security systems, packaging machine controls, timers, ultrasonic medical cleaning controls, information kiosks, queuing systems, boiler exhaust gas analyzers, traffic light systems, metal detector boards, and model aircraft electronics. We demonstrate SMD assembly in two methods. The first method is to glue the SMD components to the PCB; then to flow-solder them in conjunction with any conventional components. The second method is to screen print solder paste; then reflow solder the components. We enhance PCB assembly service with testing service using standard test equipment or purpose built test jigs, cables, and wiring loom production, product assembly, final testing and packaging service.
