Microchip Inspection Tools: Ensuring High Quality and Reliability

Mobile phones, computers, MP3 players, PDAs, gaming units – what do these things have in common? Yes, they do provide people lots of entertainment and fun time. Other than that, more on the technical side, these gadgets are byproducts of the digital technology that has been continuously evolving since the last century.

Digital items are getting more and more common these days. Manufacturers of old appliances and gadgets that people have been so used to in the past decades are now trying to make a 180 degree turn and adapt the new technology. DVDs are now the “in” thing and cassettes are out. Digital measurement readers are more preferred than their analog counterparts for more accurate readings. Makes one wonder what makes converting from analog to digital possible.

The digital technology was popularized with the introduction of microchips; otherwise known as integrated circuits. A microchip, from the term itself, is a tiny electronic circuit that is packaged to look like little chips. It is composed of several semiconductor devices that are built together and programmed to perform a specific task. Microchips were built usually for programmable logic and memory purposes. But as technology improves, they have been made for more advanced uses.

Manufacturing and Quality Control
Microchips are made up of different semiconductors and are fabricated in different processes. There are three processes involved in fabrication, which are imaging, doping and etching. After which, these semiconductors are packaged into very small containers that can be of different materials. Microchips started being packaged in ceramic materials, and later on, plastic was used.

The microchips also contain several miniature pins that serve as their data bus. These pins are very sensitive that is why these microchips should be handled with extreme care. The length, width and height of these chips need to be very accurate. The processes involved in packaging them make sure that the design requirements are religiously followed.

In order to ensure perfect compliance with the initial design of the microchip, manufacturing companies use different microchip inspection tools to do the checking. These inspection tools are usually placed on the last stages of the whole building process before the microchips are actually sealed and tagged as high-quality product. Microchip inspection tools identify physical defects on the integrated circuit, sometimes these tools can even inspect the components inside.

Some of the common physical defects of a microchip are cracks, chip on the plastic base, scratches, holes, smears or contaminations. Looking little bit closer, common flaws found beneath the microchip plastics are foreign substances, components that are misplaced or are missing, errors in plating, and discoloration of some materials.

Microchip Inspection Tools
There are different microchip inspection tools used by engineers and industrial companies to detect anomalies in their products. There are big microchip inspection machines that are integrated in the manufacturer’s production line. These machines are built with an algorithm to identify chip defects and sort them out.

One particular example of a microchip inspection tool is the MCIS 1800 series of RTS Vision. This machine performs at high speed to maximize efficiency in production. Tied with fast inspection is its high precision and reliability. It has different features such as various sorting and reporting functions, multi-language support and it is also fairly easy to use.

The same company also has other microchip inspection tools to boast of. They have the MCIS Pro which has more sophisticated and advanced features than the 1800 series. RTS also has modular device which can be integrated into a taping machine for immediate detection of body defects before and after taping.

The most common microchip inspection tool is an inspection microscope. Inspection microscopes are built just like common optical microscopes that are used in biology laboratories. These are made of a complex system of optical lenses to magnify the tiny components of a microchip. Some microchip inspection microscopes are built with the size of usual microscopes while some can be humungous.

Inspection microscopes for microchips are able to see all the six facets of a microchip – the top, bottom and the 4 sides. There are automated inspection microscopes, yet there are still some manual ones. Usually, these manual inspection microscopes are used by engineers who are still in the design stage of the microchip. They constantly inspect the prototype chips and make amendments to the design before actually releasing it to the manufacturing line.

Automated inspection microscopes are like computers on their own. They are built and programmed to inspect and sort out microchips with identified defects. This type of inspection microscopes work at a very high speed to match the production demands.

A microchip is an integral part of a digital device. This component is very sensitive and is a product of several complex processes. Each one is carefully tested and inspected under microchip inspection tools like an inspection microscope such that the end-user can be assured that the microchip in the gadget is of high quality and met the high standards of production.
