Decapsulation of packaged devices exposes the internal elements of the device under test. Opening devices by this method allows the inspection of the die, interconnects and other features typically examined during failure analysis (FA), constructional analysis (CA) and... Continue reading
![C-SAM Test](https://wpo-altertechnology.com/wp-content/uploads/2015/12/C-SAM-Test-Electronic-components-310x232.jpg)
Scanning Acoustic Microscopy (SAM) is an inspection that uses focused sound to investigate, measure, or obtain an internal image of an object. It is commonly used in failure analysis and non-destructive evaluation. The semiconductor industry has found the SAM, particularly the C... Continue reading
![Lead Integrity Test Electronic Components](https://wpo-altertechnology.com/wp-content/uploads/2015/12/Lead-Integrity-Test-Electronic-Components-310x232.jpg)
Lead integrity test is performed to determine the integrity of the device leads (terminals), welds and seals. During the execution of this test, the DUT is subjected to various stresses including tension, bending fatigue and torque. The stresses to be applied depend on the DUT... Continue reading
![incoming inspection electronic components](https://wpo-altertechnology.com/wp-content/uploads/2015/12/incoming-inspection-electronic-components-310x232.jpg)
The purpose of the incoming inspection is to identify potentially non-conforming parts, prior to placing the material in the inventory or moving it to the production flow. All parts and materials subject to receiving inspection are examined in accordance with customer purchase... Continue reading
