![]() ![]() When ready, solder the leads in to their respective pads (Red = ANODE, Black = CATHODE) Strip and twist about 5mm of the end of the leadsĩ. Cut the longer lead so that both wires are the same lengthĨ. Use a heatgun or similar heating tool to lightly shrink the sleevingħ. Cut the heatshrink sleeving in to 10mm lengths and slide one over each wire.Ħ. Be sparing with the solder so that there are no large lumpsĥ. Solder the red wire on to the ANODE leg and the black wire on to the CATHODE leg. Strip, twist and tin approximately 3mm of one end of each of the leadsĤ. Cut the CATHODE (shorter leg) to a length of about 5mmģ. Cut the ANODE (longer leg) to a length of about 7mmĢ. Where LEDs are wired with flying leads we recommend the following:-ġ. Our 4U panels are pre-drillled to accept panel-indicators from the DIALIGHT 558 series In our 4U family the LEDs are supplied already in a lens mount which is a push fit in to the front panel and are wired to the PCBs using flying leads. In our 3U family we use 3mm high-efficiency LEDs that are mounted on to the PCB (either directly or via flying leads) and are formed to sit in to a mating lens mount on the front panel. The pots come with a locating or anti-rotation pin which should be removed by snapping it off with stout pliers or cutting it off using a heavy-duty cutter (please do not use your normal cutters for this job). We occasionally, in our 3U products, use ALPHA (Taiwan) RV09 9mm pots which have the same shaft style. Our kits (3U & 4U) use ALPHA (Taiwan) RV16 16mm pots with an 8mm 18-tooth splined shaft. As always, pay careful attention to minimize the stress on the junction between the leg and the body of the component. In these cases you should form both legs as described above. Sometimes a component such as a tantalum capacitor may be supplied, for example, with 0.1” pitched legs but needs to be fitted in to a 0.2” footprint. For axial resistors this would typically be 90º. Using your fingers or another pair of pliers or suitable tool, bend the leg to the desired angle. the pliers will be holding the leg on the side nearest to the component body). The leg to be formed should be held by the pliers at a point immediately before the position the bend is to be made (i.e. A pair of small snipe-nose pliers should, ideally, be used for this task. If, however, a component is supplied or used that does not match the footprint on the pcb then you will, of course, need to form the legs so that the component can be fitted. ![]() Most components in the kits we supply are designed to be mounted directly on to the board requiring only minimal pre-forming in some cases (mainly resistors and diodes). ![]()
