Heating Observation & Measurement System Microviewβcore9046a

For those SMT engineers who look far beyond the present technologies

A reflow simulator of the coming generation to fully satisfy every requirement of heating, observation, analysis and report creation.

Re-creation of real reflow conditions

by presetting temp profiles to re-create the similar environment where such failure has developed

Visual inspection of failure

by recording the failure instantane- ously to make visual check possible

Definite diagnosis of failure mechanism

by displaying defective part’s behavior under heating on video/still pictures for analysis

Report making on an “as is” basison the software

by outputting all analyzed still pictures and other data

HeatingOutbreak of failures in surface-mounting

Observation Analysis Report making Ultimate solution

Observation only before, after heating...

The work’ s behavior is observed only before and after heating in a normal reflow, so the real cause for failure is difficult to be found.

Tremendous time to be taken for report making...

It takes considerable time to analyze heating control dataobtained in the reflow for making reports.

Not in frequent use...Not many opportunities to use it only exceptwhen there happens an SMT problem…

A small target can not be seen...Increasing magnification satisfactorily enoughto observe an ultra-miniature work is entirely impossible.

Impossible to make quantitative analysis…

You have to use another machine to measure for such analysis.

Diagnosis of failure mechanismIt helps to observe and measure the device’s defective part on recorded animations and still pictures for clarifying surface-mounting failure mechanism by quantifying displacement on various conditions.

Outputting data right out on the template Prepare the template beforehand where you can output all the saved still pictures and analyzed data to make reports instantly. You will really be free from all troublesome report preparation work.

Reflow simulator + MicroscopeIts camera set makes it possible to look intoa very small target piece. It can be used asa digital microscope if its heating unit isremoved.

Most effective convection heating method

Equipped with a convection heatingmethod similar to those of real reflows,it analyzes the measurement data of a work in the size of up to 52 x 52 mm obtained in a perfect reflow environment.

On an improper heating method...

Equipped with a heating method other than convection heating, its analysis does not always turn out to be correct.

Too complicated UI to get used to...

The UI design concept is so complicated that its users,limited in number, have a hard time getting used to its operation.

Goal-oriented UIIts goal-oriented UI makes it possible to have simpleand independent functions of heating, observation, analysis and report making, so anybody can easily use it to analyze surface-mounting data.

Heating Observation & Measurement System

Conventional SMD analysis is performed by using reflows, measuring microscopes and various other instruments. coreAnalyzer is the software designed to integrate all those conventional analysis processes into a simplified chain of “Heating”, “Obser-vation”, “Analysis” and “Report-making”. coreAnalyzer not only helps to shoot the sample’s behavior at high temperatures but also perform all other important functions which include the quantification of the behavior and the data output for making report instantly. The efficiency of SMD behavior analysis has been so greatly promoted that now anybody can easily obtain necessary data, thanks to the aforesaid functional inte-gration afforded by coreAnalyzer.

Microviewβ has further expanded its work setting area on the special glassto “52mm x 52 mm” from “39.5mm x 50 mm”, while its overall size is keptunchanged. Microviewβ also boasts the maximum achievable temperature of 400℃, increasing its heating and cooling speeds, with a new heater, 60% more powerful than those installed on Cores’ conventional Microviewα typesystems. Microviewβ can measure a maximum of 8 points as its temp loggerhas 8 CHs.

The temperature is not controlled at each zone as in real reflows but in one entire oven chamber in the case of Microviewβ. So the time required to start up and stabilize the reflow is greatly reduced.

the time taken to identify the cause of SMD defects.

The behavior of the sample can beobserved real-time at high temperatureat the very moment of an outbreak ofdefects or failure in surface mounting.So, unlike normal reflows, there is noneed to estimate possible causes ofSMD defects from the sample’s thermalchange just before and after heating.

Time required to start, stabilize the reflow is greatly reduced.

Real or normal reflows take a long time in starting up their oven and stabilizing the insidetemperature because of their temperature control at each zone. But Microviewβ significantlyreduces such required time as all the temp control from heating up to cooling down is performed in one entire oven chamber.

Aiming at similar thermal performance to that of real reflows

Historically, all of Cores’ reflow simulators have adopted a convection heating method with heat wind until today, which aim at creating in the oven quite a similar thermal atmosphere to that of real normal reflows. Microviewβ is successful in achieving its maximum temperature up to 400 as well as fur-ther increasing its heating and cooling speeds by installing a 60% greater heater in power than those of other Cores’ Microview series machines. This new change enables Microviewβ to present an evenmore striking similarity to real reflows in terms of thermal performance and efficiency.

Create your ideal temp profiles easily and instantly.

Create and set a temp profile for the sample work first, and then use the Learning Function, after heating the reflow once, to calculate the difference in temperature of the sample andthe inside oven on the software and automatically set another profile for the inside oven.

① The quality of analysis depends upon persons in charge as the cause of failure in most cases has to be presumed from the data of variation before and after heating.

② It takes considerable time to identify the cause of failure as there are many steps to do for making analysis.

① Anybody can gets the same quality of analysis as the analysis depends entirely on the videotaped data of the sample’s real behavior at high temperature.

② The sample is videotaped while it is being heated up, so unnecessary steps can be deleted such as resetting the sample.

Videotape sample not only pre/post but also amid reflowing

In the case of surface-mount analysis using a conventional reflow, the behavior of the sampleis simply compared before heating and after heating in the reflow. Therefore, presumption isthe only way to explain the process and the cause of the sample’s failure, and various possibletheories should be examined one by one for this purpose. Microviewβ brings about far greateraccuracy as well as cost reduction in such analysis because of its recording of the whole processof failure development at high temperatures, enabling you to make visual confirmation repeatedly.

Automatic videotaping pin-points really necessary sections

Preset in advance the scope of videotaping on Microviewβ, and then you won’t have to keepyour eye constantly on the screen during shooting the sample. There would be no fear of missingrecording any important section or of becoming short of data volume due to your forgetting to stoprecording.

Shooting from free angles

The microscope’s stand on Microviewβ rotates freely, so you can observe the samplefrom any angle as you like.

Analysis on “3 data” of Image, Temp, Measured value

Conventional surface-mount analysis is based on the sample’s thermal transformationdata obtained only before and after heating. Microviewβ, unlike conventional measuringinstruments, performs analysis based on “3 data” of Image, Temperature and Measuredvalue relating to the sample’s behavior obtained while it is being heated up. That is tosay, you can instantly get information as to how the sample is transformed in what quantityand at what temperature.

Animation help quantify sample’s behavior amid heatingMicroviewβ employs its image processing function to pursue, shoot and measure the sample’s behavior at high temperatures. Distances between 2 points and angels between 3 points arecalculated in animation measurement.

Still picture is of considerable utility in more detailMicroviewβ performs measurement from captured still pictures as well. Still picturemeasurement can make more detailed settings than the animation measurement andcovers those behaviors which are difficult to recognize on animations, and vertical lines,parallel lines, areas and so on.

① It takes time to input and process images and data.

② It is also difficult and time-consuming to create a test report with full output analysis data, and so all the important information cannot necessarily and sufficiently be shared within the concerned party.

① Time required to create a test report is greatly reduced, thanks to easiness in terms of outputting the images and data obtained by using coreAnalyzer.

② It is dramatically easy to prepare an effective test report in a format by utilizing a suitable template on Microviewβ for automatic report creation.

Report

Easy report productionUnlike conventional measuring instruments, Microviewβ does not require you to start from thevery beginning when it comes to preparing a test report. Create a template once by laying outcaptured still pictures and temperature data as you like, then you can continuously use the sameformat to produce your reports.

Output your report in Word or PDFYou can output your report using coreAnalyzer in Word or PDF; you can thus drasticallyshorten the time required for your report preparation.

Animations are useful in producing report, too.Data such as temperatures, measuring scales, oxygen concentrations are recorded inthe animations taken by coreAnalyzer. Those data are transformable into the format ofMPEG4 or AVI while being kept on the animations, so the animations can be fully utilized in your test report preparation.

Microviewβ’s temp logger is equipped with 8 CHs, so multiple points on the targetPCB or small device can be measured at one time.

Temeperature logger with 8 channels

Other unique characteristics

The Heating Unit heats up a sample PCB on the glass bridge, and a small device on the glass stage, the thermal capacity of which is equivalent to that of a PCB. So sam-ple measurement is performed in quite a similar thermal atmosphere to those of real reflows.

Sample setting in an atmosphere quite similar to those of real reflows

Microviewβ’ is so small–sized in design that it can be set on the table and is workable with anormal voltage of 100 VAC. Microviewβ doesnot necessitate any large space nor construction work for its smooth installation.

Low-cost and small-size oriented for utilities

Not only air but also nitrogen ormixed air with nitrogen can be usedin the reflow for heating the sample.
