TESTING PROCESS:
Kotrade's testing capabilities are comprehensive and are designed to evaluate parts through an number of test processes.
Kotrade utilizes the top US test facilities to qualify non-distribution parts from the open market. Third party testing eliminates internal "sales pressure" and ensures unbiased testing results.
Test Details
- Markings Comparison
- Visual Inspection
- Marking Permanence testing
- Solderability testing
- Acid Decapsulation
- Fluorescence RoHS compliance
- Automated X-Ray Inspection
- Electrical Function testing
Markings Comparison
Comparison of known markings to markings on parts
Utilize top markings database to compare
Older parts may have many variations due to manufacturing location or date
Visual Inspection
Using microscope for detailed analysis
Looking for signs of top coating, scratches, sanding, chips
Check leads for corrosion, bends, re-tinning, solder
BGA uniformity, no missing balls, signs of re-balling
Marking Permanence
Chemical Solvent used to remove any non-original coating and marking
Process will uncover original markings on the part
First step in catching counterfeit parts
Solderability
Test for solderability using J-STD-002D criteria
Kotrade can re-tin part for RoHS or Leaded requirements
Acid Decapsulation
Is the process of removing the external surface to reveal the internal die.
Part is compared with know gold sample or checked against die database
Destructive test and 1 part per date code is lost
Fluorescence RoHS compliance
Using either chemical or fluorescence methods
Part is checked for leadfree or RoHS status
X-Ray Inspection
X-Ray inspection reveals internal structure of part
Ensures that all bond wire strands in part are not damaged
Ball solder and void detection
Die verification, ball grid measurements
Elecrical Testing
Electrical testing to manufactures published parameters
Basic level parametric testing to Mil STD 833 level
Programming and Memory testing of over 47,000+ devices
EPROMS, FPGA, Flash Memory, CPLD, EPLD, MCU and logic devices
Depth of test is dependant on type of part
