Quality Process

Through strict documentation and procedures, the Sparqtron maintains a formalized control process that ensures the quality of every product through ever step of the process.

Our formalized quality process is not confined to volume PCB assembly - we apply it to all our services, including BGA rework/reballing, engineering change orders, PCB prototyping, and repair and upgrade services.

In separating the quality system into three distinct processes applicable to different parts of our operations, we can ensure that redundancies in quality assurance will ensure defect-free products. Each process is fully documented, standardized, and frequently reviewed for effectiveness, conformance, and improvement opportunities.

Incoming Quality Control for electronics manufacturing services

Incoming Quality Control (IQC)

It is the job of the IQC process to control suppliers, verify incoming materials, and handle quality problems before assembly starts.

Specific tasks of IQC include:

  • Perform approved vendor list check;
  • Evaluate supplier quality records;
  • Perform sampling and inspection of incoming materials;
  • Monitor Quality Control of inspected properties and alert engineering staff of deviations;
  • Continuous enhancement of the IQC process.

In-Process Quality Control for electronics manufacturing services

In-Process Quality Control (IPQC)

Our IPQC process controls the assembly and testing process, to both decrease the occurrence of defects, and to document how occurred defects should be handled.

Specific tasks of IPQC include:

  • Perform inspections on assembled and in-process materials according to IPC-A-610D standards;
  • Conduct in-line automated and manual inspections in the PCB assembly process (see our Testing Equipment page for details);
  • Ensure the conformance of process setup;
  • Utilize statistical control techniques and watch for significant deviations;
  • Perform in-process audits to ensure processes are up to standard, and to identify factors needing improvement.

Outgoing Quality Assurance for electronics manufacturing services

Outgoing Quality Assurance (OQA)

OQA is the last process before products ship to customers, and hence is every important to ensure our shipment is defect-free. Numerous redundancies with IQC and IPQC is performed here to ensure the validity of previous processes.

Specific tasks of OQA include:

  • Perform visual and functional inspection;
  • Apply sampling-based or 100% inspection;
  • Conduct reliability testing;
  • Submit failure analysis reports and alert engineering staff.
