Inovar Invests in MIRTEC’s SPI Systems to Decrease Solder Defects

Reading time ( words)

Inovar, Inc., a full-service EMS provider, announces that it recently purchased and installed four MS-11 solder paste inspection (SPI) systems from MIRTEC.

The SPI systems currently are in use at Inovar on its three production lines as well as its prototype line.

Jef Nielsen, Process Engineering Manager, said that the systems allow Inovar to recognize problems with the application of solder paste onto the printed circuit boards (PCBs) in real time. The SPI machine is located directly after the screen printer machine in the production line. He added, “It is industry knowledge that a high percentage of solder defects can be attributed to problems with the solder paste application. These machines will quickly detect any deficiencies and allow for quick modifications to reduce the defect potential.” The machines also have statistical process control (SPC) software to track defects, thereby identifying the most problematic assemblies and defect types.

The MS-11 systems are configured with MIRTEC’s exclusive 15MP CoaXPress Vision System, providing enhanced image quality, superior accuracy and incredibly fast inspection rates. The high-speed precision In-line SPI system uses dual projection Shadow Free Moiré Phase Shift Imaging Technology to inspect solder paste depositions on PCBs post screen print for insufficient solder, excessive solder, shape deformity, shift of deposition and bridging. Featuring an exclusive 15 mega pixel ISIS® vision system, the MS-11 series provides 10 micron/pixel precision telecentric compound lens design, 2 micron height accuracy, a precision closed-loop servo motor system, and extremely simple programming and operation. As an additional benefit, the systems provide MOIRÉ 3D phase step image processing, superior solder profile characterization, absolute repeatability and reproducibility, and precision laser PCB warpage compensation.

This Month in SMT007 Magazine: Test and Measurement in a Smart Factory

11/03/2020 | Nolan Johnson, I-Connect007
Nolan Johnson spoke with MIRTEC President Brian D’Amico about how the role of test and measurement equipment is changing in the smart factory and how shops can adjust to make use of the new technology. D’Amico shares this insight: “While approximately 90% of U.S. electronics manufacturers recognize the potential of Industry 4.0 to improve productivity, many are slow to adopt smart factory solutions within the manufacturing process.”

Reducing Flux Splatter in Sensors and Camera Modules

10/30/2020 | Jasbir Bath, Shantanu Joshi, and Noriyoshi Uchida, Koki Solder America And Koki Company Limited
With the increased use of electronics in new technology areas, flux formulations are being developed to address the new and existing requirements. For sensors and camera modules used for Advanced Driver Assistance System (ADAS) and internet of things (IoT) applications, there is a demand for no-clean flux formulations in lead-free solder paste, which can reduce flux splattering during reflow.
