New AOI & SPI launches at Productronica

ISO-Spector M1 3D AOIWe are busy preparing for the forthcoming Productronica show in Munich where we’ll be launching a whole host of new AOI & SPI systems across a very wide range of applications and budgets. The Mek team will be on hand at Hall A2 stand 402 to host demonstrations of unique capability.

Mek ISO-Spector M1, featuring the latest in 3D inspection technology, will be our flagship launch at the show. A metrological AOI system of true measurement, the M1 delivers full, across-the-board height profile measurement and inspection. Carrying the industry’s largest, 25 mega pixel sensor and 69 x 69mm FoV the M1 delivers ultra-high speed inspection of even 008004 components, leads and solder joints. Multiple Moiré fringe projections enable high precision, shadow free measurement of heights up to 30mm as well as 4 fully programmable side view high-res cameras able to actively inspect Jleads and other devices invisible to top side imagers.

Other product highlights at the show include:

SpectorBOX GTAz 550
“Bottom Up/Top Down” AOI system

iSpector JDz 520
New entry level AOI boasting high specifications, including a 5 mega pixel camera, 15 micron telecentric lens, Co-Axial light and 520 x 460mm max. PCB size

ISO-Spector S2
New SPI system with patented third generation sensor technology that enables simultaneous 3D and 2D (5D) 2D and 3D inspection

PowerSpector GTAz+GDAz 550LBT
Double sided AOI with in total 18 camera’s

3D Measurement & 3D AOI

ISO-Spector 3D AOI

Mek ISO-Spector series delivers a genuine, FULL 3D inspection

3D measurement is the latest development trend in assembled PCB inspection. It’s creating quite a stir and it does indeed offer many advantages in terms of improved accuracy & stability of inspection results. Having quantitative data gives much tighter control than “classic” AOI and is a big step forward in improving the quality assurance and process control of assembled PCBs.

Unfortunately, the term ‘Full 3D’ is often used inaccurately. Full 3D implies that the height profile across the whole PCB is being measured, but most of the time, the majority of systems can only measure height selectively, and only on component bodies, NOT the solder joints. And even then, only the components that the programmer has specifically identified and selected for height measurement. For the remainder, classic 2D algorithms and lights are used for the inspection.

Our 3D AOI solution, the Mek ISO-Spector series delivers a genuine, Full 3D inspection that measures a complete height profile across the whole PCB, including the solder joints. As solder joints are shiny, as are some glass or cylindrical shaped components, it can be quite difficult to measure their heights because projected light beams reflect in all directions. But Mek has successfully overcome that challenge.

ISO-Spector uses dual, telecentric, violet color, almost vertical (80 degrees) laser projections and a specially developed 12 mega pixel capturing sensor that can measure 3D but also capture 2D images simultaneously. Its’ powerful software enables what is probably the fastest programming time in 3D AOI.

Compared to the PowerSpector selective 3D AOI systems, used by many Mek customers, the ISO-Spector is completely different from both a hardware and software point of view. But the PowerSpector range has also been greatly developed recently and latest generation models (GTAz) have 9 cameras (1 main and 8 side) and standard Z-Axis. The side cameras can be used for active inspection next to comfortable verification of defects. But the biggest feature is that the multiple cameras can be used for height measurement using the stereoscopic method on the bodies of passive components for coplanarity tests.

Which type of system is the best fit for you and your manufacturing facility is dependent on a number of factors. What sort of production is taking place? High mix/ low volume? Are you looking for an inline solution or desktop? What are the max PCB dimensions you are looking to work with?

We have demo ISO-Spector and PowerSpector units in our showroom in the Netherlands where interested customers are highly welcome as visitors. We’d love the opportunity to demonstrate their capabilities and help you in making the decision on what type of AOI you really need.

Meaningful SPI Production Control Through Automatic Normalization

Automated pre-placement solder paste inspection (SPI) has established itself in SMT assembly as an essential tool for optimizing the process and reducing end of line defects.  It’s been commonly accepted for many years that a majority of assembly defects can be traced back to print defects, and by using raw measurement data from printed PCBs for volume, area, height and offset, SPC histograms and control charts can quite readily be used to optimize the process.
