DIVaero is defined and driven by the following management principles and behaviors:


  • To provide a means for our customers to achieve the objectives to attain their customer’s desired product or service.
  • Assisting our customers by transforming their needs and requirements into actionable industry language and procedures that result in fulfilling their product or service outcome.
  • Achieve Customer Satisfaction by meeting the project requirements defined in our statement of work to the quality level the customer requires.
  • Management’s commitment is to develop and encourage staff competencies, creativity, and accountability through involvement.
  • Commitment to Continual Improvement by promoting and raising the competence level of our staff.  This can be achieved by attending seminars, ongoing education, independent research, and experimentation.

 

LAB SERVICES

The technical staff and laboratory came from Diversified Systems (40+YEAR COMPANY), which was a MIL 31032 QML listed PCB FABRICATOR, PCB assembler and laboratory

The Laboratory performs A-600 inspection and evaluates the technical specifications for compliance to IPC

A board level evaluation may include (but is not limited to) :

Cross section for Copper thickness

Hole quality (Via hole and Component hole)

Thermal Stress and Solderability

Hot Oil De-lamination 

Cleanliness testing

o   Modified Rose

o   Ion Chromatography available for specific Ion testing

·        Bare Board (electrical) testing to the IPC-D-356 Net List

o   500V testing available for Specific applications such as Military.

·        DSC laminate evaluation for the Tg

·        XRF for the thickness of the surface finish (Gold, Nickel, Silver, Tin, HASL)

Additional Laboratory Services may include:  Process Consulting, Failure Analysis, and Technical Training.

LABORATORY FAILURE ANALYSIS

Assembly Failure Analysis is based on a combination of X-RAYs followed by cross-sectional analysis.  Microsection is performed on the part and the solder connection to best view the metallurgical attachment and/or failure using successive grinds with measurements and pictures (Keyence 2000X microscope) at each grind depth.  We then stress and fracture components to observe the failure mechanism.  This tells us if the solder joint is stronger than the attachment of the copper land to the PCB.  Once the solder connection is stronger than the PCB pad adhesion, the joint is strong enough.  If needed or requested, the lab will use one of the chambers to perform thermal shock, which (again) is analyzed by microsection after the shock.

REFLOW ANALYSIS

Reflow analysis is based on the metallurgical bond that was achieved and the flow of the solder paste.  For a BGA, the ball collapse and the attachment of the ball to the interposer board and the PCB are analyzed with a microsection.  We have 3-D X-Ray that performs a 360-degree CT scan.   Ultimately, the extent of the intermetallic formation is viewed from the microsection.

ASSEMBLY ANALYSIS

DIVaero Lab follows J-STD for acceptability of the solder and IPC A-600 for the Assembly.  We “fracture” select components to determine the failure mechanism.  We have developed standards for fracture force (these are not recognized by the IPC, but we have found them to be very predictive of performance).

REPORTING OPTIONS

For simplicity and cost, the basic report accompanying a Laboratory project will employ a combination of pictures and a basic explanation of the pictures.  All data, including the pictures is in an Excel file.

If a formalized report is required, one is prepared with the report having excerpts from the Excel data for further clarification.  The final report is in a MS Word format that is captured in a .PDF and written by the Laboratory Manager or Technical Services Director.

PRICING

Pricing is simply the hours required for the task multiplied by the rate for the resource (person or machine).  A quotation can be prepared, or a time and materials PO may be issued. 

LAB EXPERTISE

All lab personnel have more than 20 years working in a 31032 QML listed PCB lab.    However, all Assembly related analysis is referred to the Senior Technical Advisor (a Registered Professional Engineer) that has more than 40 years of assembly experience.  It is the combination of the expertise to perform very precise microsections and the analysis of senior experts in Assembly that make the lab unique.

DUAL BACKGROUNDS IN PCB FABRICATION AND ASSEMBLY

All of the technical resources have dual backgrounds in both Assembly and PCB.  This combination of hands on experience in both PCB fabrication and PCB Assembly is extremely uncommon.  However, it allows DIVaero to assist customers with problems in Layout, PCB Specification, or Assembly Processes.  This assistance is part of the value proposition that DIVaero offers to all customers.
