Have Own Factory——Reliable And Quality Guaranteed
As a professional PCBA service provider with 18 years of deep expertise in the electronics industry, TORTAI Technologies Co., Ltd. possesses a thorough understanding of the manufacturing challenges faced by OEMs and has built a systematic framework to ensure your products are robust and reliable from design through delivery.
Located in Humen, Dongguan, TORTAI Technologies operates a 4,000m² modern manufacturing facility equipped with 4 fully automated high-speed SMT lines and 2 DIP lines. We are certified to ISO9001:2015, ISO13485, ISO14001, and IATF16949, and strictly adhere to IPC-A-610J Class III acceptance standards.
Proactive DFM Collaboration: Eliminating Risk at the Source
We don’t simply enforce strict standards on the manufacturing floor — we intervene proactively at the very inception of your project. Our engineering team conducts an in-depth Design for Manufacturability (DFM) review, offering optimization recommendations on component selection, PCB layout and routing, and thermal management. The goal is to enhance manufacturability, testability, and long-term reliability. For example, by optimizing the layout to minimize signal interference or recommending more suitable component alternatives, we effectively prevent up to 80% of potential manufacturing issues right at the design stage.
Closed-Loop Quality Control with Full Traceability
Our capabilities span complete SMT (Surface Mount Technology) and DIP (Dual In-line Package) production lines, supported by a rigorous multi-stage quality control process. From solder paste printing (SPI inspection) and precision placement (in-line AOI) to reflow soldering (with strict temperature profiling) and wave soldering, every stage includes its own inspection checkpoint (IPQC). Critically, we have deployed a comprehensive MES (Manufacturing Execution System) that assigns a unique traceability code to every single PCBA, recording all material batch numbers, process parameters, and inspection data. This ensures full compliance with the stringent traceability mandates of the medical, industrial, new energy, automotive, telecommunications, and security electronics sectors, guaranteeing that any issue can be quickly localized and traced back to its root cause.
Supply Chain Control & One-Stop Service Assurance
We have built a diversified and transparent component supply chain, working closely with multiple original manufacturers and top-tier distributors. This provides reliable backup supply sources for critical materials, effectively mitigating the risk of shortages. We offer a complete one-stop service encompassing design support, component procurement (with approved substitutions), PCBA manufacturing, product testing, and custom packaging. You simply provide your design files (Gerber, BOM, etc.), and we deliver fully compliant, finished boards. This significantly reduces your burden in supply chain management and quality compliance, allowing you to stay focused on your core R&D and product validation.
Excellence Begins With Every process
12 inspection procedures forge excellence
 |
 |
 |
 |
|
Incoming Quality Control (IQC) Purpose: To implement stringent quality control over materials supplied by vendors, ensuring that components entering the production process meet specified standards. This prevents process defects arising from substandard materials and minimises time losses caused by the use of refurbished materials that fail to meet quality requirements. |
Solder Paste Inspection (SPI) Purpose: Employing advanced optical inspection technology to conduct comprehensive assessment of solder paste printing quality, enabling early detection of defects such as insufficient paste volume, misalignment, and bridging to prevent defective products from progressing to subsequent processes. |
In-line AOI Inspection Purpose: Utilising advanced machine vision technology to perform automated optical inspection on products during production. This enables rapid and accurate identification of defects such as incorrect parts, missing components, and reversed parts, whilst intercepting substandard materials before they enter subsequent processes. |
First Article Inspection (FAI) Purpose: To verify the correctness of the assembly process on the production line and ensure that the parameters of each resistive and capacitive component (such as resistors, capacitors, etc.) fall within the specified standard range. |
 |
 |
 |
 |
|
IPQC Purpose: To conduct random inspections of all production processes to verify compliance with work instructions. |
Offline AOI Inspection Purpose: To inspect surface-mounted PCBA assemblies post-soldering for defects such as missing components, reverse soldering, and short circuits in accordance with the IPC-610D standard. |
X-Ray Testing Purpose: To inspect solder joints on components invisible to the naked eye, ensuring the reliability of each solder ball on BGAs. |
In-Circuit Test (ICT) Purpose: To swiftly and accurately identify various defects arising during the manufacturing process after PCB assembly is complete, thereby ensuring product quality and reliability. |
 |
 |
 |
 |
|
Functional Test（FCT） Purpose: To simulate the product’s ultimate real-world operating environment by conducting power-up testing on assembled PCBA units or complete systems, verifying that their functionality, performance, and behaviour fully comply with design specifications. |
Manual QC Inspection Purpose: To conduct rigorous manual inspection of finished boards in accordance with the IPC-610 inspection standard, ensuring 99.98% of products shipped are of acceptable quality. |
QA Outbound inspection Purpose: To conduct rigorous inspection prior to dispatch and verify via barcode scanning, thereby preventing non-compliant products from being shipped. |
ESD-Safe Storage & Shipping Purpose: To ensure anti-static packaging and provide safe protection during storage or dispatch operations. |
