Our process of visual inspection begins with product handling.  All inspectors must take and pass the Electrostatic Discharge Sensitive Safety Standard (ESDS) on their first day of employment and continuously be retrained.  This knowledge is critical for receiving inspections and shipping preparation.  Our inspection work stations are state of the art, equipped with dinocam microscopes, digital cameras with macro capability, scales, handling tools, bar code scanners, multiple magnifiers, reel to reel counters, measurement tools and humidity control supplies such as vacuum sealers, desiccants, humidity indicator cards and room humidity monitors.  Package inspections includes photos of outside labels, photos to assure no damage to outer package, properly sealed, correct date codes, correct manufacturer logos, bar codes scanned and photos are uploaded to database for each order.  Interior contents are inspected for proper quantities, date code/lot codes, manufacturer, part number, and condition of all surfaces.  All parts will be subjected to datasheet references for package and configuration dimensions, resistant to solvents using 3:1 mineral spirits/alcohol solution, acetone and scrape test. 

After completion of visual inspection all parts supplied toindustries will receive full component authentication via our in-house, certified test labs.  These tests will include Real-Time X-Ray Analysis, XRF Elemental Analysis, Scanning Electron Microscopy (SEM), Heated Solvent Testing, Decapsulation and Die Microscopy and Solderability Testing, all documented on an extensively detailed report.  In-house value added services can include tape in reel, dry baking, DNA Marking and Electrical Functionality Testing.

Before any employee is allowed to enter the component inspection, testing, packaging or warehousing areas, they must first pass through a custom designed “ESD Airlock System” and pass the ESD training guide exam.

This mandatory electronic test point (ESD Airlock System) monitors both footwear and wrist straps testing proper position and grounding before the ESD test system will release the electric door strike. This acquired authorization grants access to critical component handling areas.

Our Quality Technicians rigorously inspect and document all incoming and outgoing components for proper packaging, condition, count, authenticity and overall quality.

To track inventory movement throughout the warehouse, We uses the latest warehouse barcode scan system from Symbol Technologies. This software tracks every piece of crucial information: bin locations, manufacturer information, part numbers, FIFO layers, quantities, date codes, order numbers and customer internal part numbers.
