  2. INTRODUCTION Ensuringthereliabilityandoptimalperformanceofelectronicproductsisessential for electronics OEMs. In their pursuit of excellence, these manufacturers recognize the crucial role that printed circuit boards (PCBs) play in the performance of electronicdevices.DefectsinPCBscancausedevicemalfunctionsorfailures,which iswhywe,atSuntronic, Inc. provideawiderangeof electronicstestingservicestoaddressthisissue. Ourcomprehensiveselectionoftestingservicesincludesvarioustypesoffunctional testing and burn-in testing. By subjecting all PCBs and PCB assemblies to meticuloustesting,wecanidentifyandrectifyanypotentialdefectsbeforeshipping the products to our customers. This proactive approach ensures that our clients receivehigh-quality,reliablePCBsthatmeettheirexactingstandards. Page02of11

  3. Overtheyears,wehavedevelopedarangeofelectronictestingcapabilitiesthathaveenabled ustoupholdourcommitmenttoprovidinghigh-qualityproductsatcompetitiveprices.These capabilitiesinclude: ELECTRONICTESTINGCAPABILITES 01 BURN-INTESTING 05 AUTOMATEDOPTICAL INSPECTION(AOI) 03 IN-CIRCUITTESTING 06 DESIGNFORTEST (DFT) 02 FLYINGPROBE 04 X-RAYINSPECTION Page03of11

  4. Toassessthereliabilityandlong-termperformanceof BURN-INTESTING electronicdevices,weemployburn-intesting.This the rigorous testing process involves subjecting productstoelevatedtemperaturesandstressconditions foranextendedperiod.Bydoingso,wecanidentifyany latent defects or weaknesses that may arise over time, ensuringthattheproductwithstandsdemanding operationalenvironments. By employing the burn-in process, we can mitigate the riskofprematurefailuresandenhancetheoverall qualityandreliabilityofourproducts. Page04of11

  5. Thistypeoftestingisanimprovementofthebedof nails testing and requires no permanent fixture, which makes it inexpensive. It is a tried and trued PCBTestingMethod. A flyingprobe machine can accessthe ends of components or unintended vias as test points. The machine can be programmed to check the value of passive parts, their voltage measurements, and the transistor/diodeorientation.Thismethodisvery accurateandcanmeasurevaluesat99%accuracy.

  6. During in-circuit testing, the PCBAs are testedwhiletheyare stillassembled, withtheelectricalcomponentsmounted IN-CIRCUITTESTING ontheboardandconnectedtothe the circuit. The purpose is to verify correct installation and connectivity of the components, as well as to check for any faults such as open circuits, short circuits,orincorrectcomponentvalues. In-circuittestingisaneffectivemethod forquicklyandaccuratelyidentifying manufacturingdefectsandensuringthe qualityofPCBAs. Page06of11

  7. As the name suggests, this type of testing is performed usingX-rays.We employX-ray systemscapable of2Dand 3Dinspection workflow.TheX-rayinspection isideal for inspecting hidden joints in underside pads andballgridarrays(BGAs). TheX-rayinspectionhelpsdetectsoldervoids and has one of the highest detection rates of faults, which are not otherwise detectable by inspection. X-RAYINSPECTION Page07of11

  8. AUTOMATEDOPTICALINSPECTION(AOI) Theautomated optical inspection (AOI) uses 2D or 3D cameras to take images of thePCB.Theimageiscomparedwiththe images of PCB design being tested and the database of images of bad and good boards. TheAOImachinecanbeintegratedatthe endoftheproductionequipment. It helps detect major solder defects, and is suitedfortestingmature productsin largebatches. Page08of11
