SMTNW has built its EMS quality management process around preventing problems before finished assemblies reach the customer. Since 1996, we have helped our customers produce high-quality electronic assemblies through a combination of advanced automation, rigorous inspection processes, inventory control, and proactive communication at critical points in the process. We build quality into our electronic manufacturing capabilities, from sourcing and setup through inspection and delivery. As a result, our processes deliver a 98% first-pass yield, helping customers reduce rework, avoid production delays, and maintain product quality through the manufacturing lifecycle.
EMS Quality Management
Quality Starts Before Production
An effective EMS quality management system is an end-to-end framework governing design, supply chain, production, and lifecycle support. Before production starts, our quality system is active as we review project files, bill of materials data, CAD data, Gerber files, and customer requirements. When information is incomplete or unclear, we ask questions rather than making assumptions to push the product out the door.
EMS quality management depends on controlling what enters the process. We perform DFM evaluations, identify hard-to-find or obsolete components during the RFQ and procurement process, use approved manufacturer part numbers, and obtain customer approval before using alternate sourcing. We use this approach to limit exposure to counterfeit components and keep customers involved when a sourcing decision could affect the finished product.
EMS Quality Management at Every Stage
Limiting inspection to the finished product is too late in the process, so we use multiple inspection stops and quality-focused procedures throughout production. Our comprehensive quality management procedures are designed to reduce defects and improve traceability throughout production.
Our end-to-end quality processes include:
- Incoming component verification
- Approved sourcing to reduce counterfeit component exposure
- Obsolescence and hard-to-find component identification during RFQ
- Customer approval before using nonstandard or alternate sourcing
- ERP / inventory control validation before release to production
- Kit validation
- Secondary validation of customer consigned kits
- Shortage sheet creation for missing kit components
- Complete pre-production job audit
- Physical part identification before production
- Digital production documentation
- First article inspection on every new setup
- 100% 3D AOI inspection for SMT assemblies
- X-ray validation
- Multiple inspection steps throughout production
- Post-soldering inspection
- Post-mechanical assembly inspection
- Rework process for difficult assemblies
- Customer feedback review
- Corrective response process when quality issues occur
In addition, our inspectors are IPC-A-610 certified, and our assemblers are J-STD-001 certified. The result is a 98% first-pass yield, fewer assemblies waiting for rework, fewer surprises at receiving, and a more predictable flow of finished product to our customers’ end users.

Communication That Supports Quality
Achieving a good quality result also depends on communication. If a bill of materials, drawing, handling requirement, cleaning instruction, packaging expectation, or design detail raises a question, we ask for clarification. Our internal philosophy is to ship the customer the high-quality product they need, without taking shortcuts or making assumptions.
Customers receive updates at critical points in the process. Delivery schedules are regularly discussed, production issues are communicated before delivery, and recommendations for design or process improvements are shared when relevant. If a question comes in, the team responds quickly, even if the first response is to confirm that the RFQ or issue has been received and is being reviewed.
Quality Management for High-Reliability Industries
Quality management is most critical when a PCB assembly failure can create more than a rejected part. In regulated and performance-sensitive industries, poor component control, undocumented substitutions, missed inspection steps, or incomplete production records can lead to noncompliance, field failures, delayed approvals, warranty exposure, and costly rework.
SMTNW supports customers in industries where reliable electronic assemblies, documented process controls, and clear production communication are critical to the finished product. Our quality process helps reduce risk from sourcing through delivery, giving customers the traceability and inspection discipline needed for complex electronic manufacturing programs.
