- DIE Verification
- Solvent Testing (Resistance and Heating)
- Solderability Testing
- Failure Analysis
- EXTERNAL VISUAL TESTING SERVICES
- While product variations do not necessarily mean counterfeit components, Chearf Electronics Co.,Ltd is always vigilant. Because we truly understand manufacturer supply chains, engineering controls and the manufacturing process, we know when variations are evidence of counterfeiting or something unique to the manufacturer.
- XRF SCREENING
- (Restricted materials testing) The EU RoHS Directive (2011/65/EU) restricts the maximum allowable levels of lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyl (PBB) and polybrominated diphenyl in electrical equipment and electronic products. XRF is a non-destructive x-ray test that helps detect the presence, or absence, of these materials.
- MARKING & PERMANENCY TESTING
- Counterfeiters often have unauthorized access to scrap or excess components. Marking and permanency tests help determine if these components have been remarked or resurfaced. Marking and Permanency tests are based on the following industry standards: AS5553, MIL-STD-202 and JESD22- B107C
- JTAG TESTING
- With our JTAG / Boundary Scanning we are able to utilize thousands of test points using only four test access points. They enable us to test connections between the pins of ICs.
- RADIOGRAPHY (X-RAY) TESTING
- Chearf Electronics Co.,Ltd uses real-time X-ray technology to examine electronic components. Xray inspection is a non-destructive test that verifies the bond wire connections and offers a chance to perform die size comparisons.
- SOLDERABILITY TESTING
- Solderability testing allows us to determine whether a component can be successfully soldered onto another surface in the next level assembly using SnPb or Pb-free solder. We follow the joint standard J-STD-002 accept-reject criteria for all thru-hole, surface mount, and BGA devices.
- DECAPSULATION/DELIDDING
- Decap" is a "destructive test" that helps verify the manufacturer die to ensure that it is indeed the correct one. The component's insulation package is removed to reveal the die and is viewed under high-power magnification.
- PRE-SHIPMENT INSPECTION
- Chearf Electronics Co.,Ltd's pre-shipment inspection process is a systematic inspection of randomly selected components from your order. It is the final phase before your order ships and allows us the opportunity to take corrective action before your order is packed.
