TORTAI are experts in designing, engineering, and manufacturing of printed circuit boards. For more than 18 years, we have developed our expertise and worked with clients across different industries to deliver the very best in PCB assembly services. Our own PCB assembly technology experts partner with some of the best PCB manufacturers. Over the years we have been serving our clients, we have built strong relationships with each of our partners. Our team can help with a range of PCB assembly needs, ensuring all of our clients are satisfied with the results that they receive from our services.
TORTAI strictly adheres to the IPC-A-610 quality control standards. To better control the soldering quality of the products, it is equipped with a three-dimensional solder paste inspection device (3D SPI), a fully automatic optical inspection instrument (3D AOI), an X-ray detector, and high-definition microscopes, among other complete quality control equipment for the SMT process.
Each SMT production line is equipped with a fully automatic optical inspection instrument (3D AOI), which can detect various defects such as component offset after welding, insufficient soldering, short circuit, contamination, missing parts, skewing, standing upright, side-up, flipping, wrong parts, damage, floating height, polarity, open circuit, no soldering, overflow glue, tin holes, and pin not protruding.
Additionally, we have deployed high-capacity, high-resolution, and high-magnification X-RAY inspection systems to ensure the soldering quality of BGA components.
TORTAI Offers a free DFM check that can help customers avoid obvious mistakes.

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. |
