Mr. JB withhis Scanning Electron Microscope
JB is pet name of Jung-Bum Chun，whose Korean name is 전정범 and Chinese nameis 全正范. Mr.JB is a doctor，he is the inaugurator and CEO of Emcrafts Co.,Ltd.，a small company which is self-proclaimed as the Korea’s leading SEM（ ScanningElectron Microscope）manufacturer.Mr.JB is the designer of Emcrafts SEM. To date，the author’s known Mr.JB more than 5years, and met with him dozen times.
The author has found the ad. Information of emcrafts at Baidu paid-listing as far back as the beginning of 2014. It was curious how the emcrafts become a leading SEM’s Brand which was never heard. The author didn’t like it so much for its pretty bragging, many people maybe have the feeling likewise.
The author didn’t know until a Korea friend mentioned that emcrafts is a small Scanning electron microscope company found by Mr.JB,the ex-CTO of coxem .[Mr.JB serviced as CTO in COXEM from Nov. 2007 to Oct.2010，and he found emcrafts in Nov. 2010.]
That korea friend introduced the author to Mr.JB in Aug 2014.Shortly. A warm mail from Mr.JB said that most coxem’s SEMproducts including CX-200 and EM series table-top SEM were his work，indicatedhis strong experience in SEM R&D; invited the author to browse his corp’s officialwebsite, said that the author would have got to know its SEM product was muchmore competitive in all over the world. [Now the author think back Mr.JB’s words，the potential means is that it must go to hell if the author couldn’t get toknow after viewing! Because Mr.JB’s urine always hasbeen so. If interested，please read on ]；invited the author to visit his product display at 2014 SuzhouNano-exhibition in China.
Speaking of the earlier model CX-200 and EM table-top SEM of COXEM the author touched, that can not talk more, otherwise it will be full ofabsurd words and handful bitter tears. COXEM was found in 2007 as far as theauthor know, the original SEM’s technology camefrom KRISS, a scholar who is full of emotion with Electron Microscope was thechief researcher，the resolution performance of prototype CX-100 SEM they offeredwas pretty good.
The author had browsed the official websit of Mr.JB’s corp andheld a skeptical attitude. Mr.JB omitted all the SEM image information smartlyin the title bar of application. The imaging quality can not be judged via thisimages.
As for investigating precise instrument like SEM at exhibitingbooth, normally one can not test the real performance status in noiseenvironment, watch the scene of bustle merely.
Base on the reason above，the authorreplied Mr.JB，not learned at the booth of exhibition，but hoped tovisit EMCRAFTS and test its SEM in its Korean factory specially.
While Mr.JB expressed always welcome the author to his factory，but seemedhesitated slightly，as if he could be sure the author would have been satisfied with itsSEM product after visiting its booth of exhibition.
Soon after，the author reached Seoul, retraced the map,checked-in the hotelwhich Mr.JB had helped being reserved. The next morning，Mr.JBemerged at the door of the guest room, with the same age and nearly high andsize of the body，although meeting at the first time，there wereno more formula and formality each other. And then，the authorsat into Mr.JB’s Sonata-8 which was driven from a alley.
Mr.JB loved learning，he entered a not badprivate university in 1992，obtained two bachelor diplomas till 1998. He obtained master diplomain 2000，and then began his doctor career，finally gothis Dr. degree in 2009. Maybe full of sth in his body，Mr.JB’s bottom isuplift toward back slightly，his chest out，and feeling his face toward the sky. The author was not a goodstudent, graduated from a noteless university in 1996. Mr.JB asked closely forthe exact name，Mr.JB feel very funny after the auther told him.
The conversation then turned to COXEM which both sides hadexperienced, on which both sides wouldn’t like totalk more about the right or wrong. The author came here chiefly focusing theperformance of Mr.JB’s SEM, so mentioned the past and now of EM table-top sem, describedhow about the original technique，and how about thetechnique then time, coxem made great progress.The author thought thedescription is objective, only wanted to hear the comment from Mr.JB around thesimilar market. Mr.JB responded contemptuously，said thatthere was no one understand SEM in COXEM after he left，and theCEOof coxem was only a marketing person. so he couldn’t believecoxem’s great progress. The author also mentioned that expert of KRISS whohelped COXEM，however，Mr.JB responded only scornful smile. The author perceived subtlythat Mr.JB’s impression to coxem was the time when he had been there，and Mr.JBmight be annoyed slightly with the author’s lowerevaluation to his works.
Mr.JB’s thought was still stucked in 2years ago at least. The author wasmaking SEM market study and doing all the work like technical support、sales、installation、trainingcustomeretc, having some right to speaking on COXEM’s EM. Theauthor has experienced numerous version of EM table-top SEM which has beenreached the best status of this kind of SEM till 2014，the hardwareand software has been changed thoroughly except the cover shell designedoriginally. Coxem’s then CEO was open-minded leader with good leadership and sincereunity of all the cooperator，which deeply won the trust and support from the capital side. To beobjective，coxem's SEM met to the market requirement, the quality andperformance has been pretty competitive in 2014.
It was no matter that Mr.JB’s idea ofSEM R&D was stucked in two or even twenty years ago，for sincepast 20 years，the core performance of tungsten- SEM hadn’tbreakthrough from the view of electron optics. The performance of theKorea leading SEM of which Mr.JB was proud would be revealed right now.
The author reached a place like innovation park where Mr.JB’s factorylocated and the environment was quiet. The workplace was on the ground floor，several room，coveredabout 100m2,where the author met 3-4 staff.
The results of testing was not ideal. The author indicated theimaging quality which Mr.JB declared 3nm resolution of the Genesis SEM wasworse than then EM-30, and some operational mode was lag also. The author meantthe insufficient competitive about Mr.JB’s SEM. Theevaluation given by the author must be lower obviously than Mr.JB’santicipation, that made Mr.JB being unhappy was obvious also.Mr.JB saidthe worse performance due to worse environment，any producthas pros and cons,etc. In the author’s mind，there aresome international standard or general principles for the sem performance, theSEM designer or manufacturer should have respected more or less，that was notonly pros and cons question. Of course，the negativerespects can not be spoken always，otherwise，the authorwas likely kicked out of Mr.JB’s company.
The author admitted the Genesis had some strengths. Mr.JB wasrefreshed by the recognition，began to boast thatthis kind of compact SEM was created first time by him，small sizeand light weight，could be raised up by four strong man，was imitatedby another competitor after its launched，and hisproduct was the most economical，very cheap. Theauthor was convinced，if speaking so，didn’t thetap-top sem have more advantages?
The author asked Mr.JB how many units were sold. Mr.JB respondedwith somewhat dejection，said that was company’s secret，couldn’t believethe author yet，his company was always profitable，sold alittle company shares if really short of money. In short，Mr.JB letthe author know his company can live on . Above speaking was understandable，but Mr.JBwas keeping secret to the author after cooperating formally when the authorrequired some customer list to promote contract. The taste was not right.
The author neglected or paid deficient attention to some parts atthe first testing，hoped to learn it the next day. Mr.JB，however，refuseddecisively，said he had demonstrated enough. Today，it wasregretted that the author couldn’t test again, ifnot,Mr.JB might have been provoked，kicked the authorout directly，then the world would have been quiet.
Actually，traditional big SEM was miniaturized，themanufacturing cost is similar with table-top SEM，theperformance is better than table-top SEM which was packaged into abox overall, the market space is not small if the design and manufactureis precision. But if the advantage can not be applied or the quality andperformance is lower too much, that is another question. The author thoughtsubjectively that Mr.JB improved his product must not be difficult thingsbase on korea basic industry, to change the structure，must beeasier.
The author’ssubjectivity and touched by Mr.JB’s independentfearless spirit which was rare in EM realm， plus Mr.JB’s commitmentfor improvement, the author decided to communicate and cooperate deeply withMr.JB，but undiscovered Mr.JB’s barefaced portion.
In order to confer and enhance comprehension mutually，The authormet Mr.JB again at 2014 Suzhou nanotech exhibition in China.
Mr.JB’s booth which was likely sponsored by Korea government was a goodstandard size at corner. Mr.JB led almost all his staff to exhibitceremoniously his latest work，genesis-2000 SEMwhich was fitted motor driver stage with its infrared video monitor.
The author participated as a spectator around the booth, casuallymet a past potential customer who came back from U.S. and had ever seen much ofthe SEM. The potential customer asked if the author wanted to cell Genesis SEM，and thenexpressed definitely his dislike to genesis structure after the author told himhaving no idea yet. An old gentleman had some interest，took for theauthor belong to the booth, asked the particle size in the SEM image ofdisplayboard. Because the SEM image’s information wasomitted nearly in all the promotional material designed by Mr.JB, that might befor the need of secrecy.Who knew？Asked other staff，all unaware，asked Mr.JB，he forgotalso. The author thought privately that this promotion was really valid，could filterout the potential customer with a little bit of interest instantly.
As if a lot of money revolving around Mr.JB，JB was fullof confidence，bathing in the breeze and clear sky，hung theword “make a fortune”on his mouth.
Mr.JB never admitted the existing problem was question，butsimplifed those problem as pros and cons, Strength and weakness, committedtrippingly the improvement of weakness.
The author and Mr.JB started the discussion for agent in China. Thegenesis SEM’s resolution was not enough very much to support 3nm declared in JBcompany’s website according to the specific test. The author required Mr.JBto change the model name if Genesis-1000/2000 was sold in China market, the newmodel SEM would be marked 5nm resolution. Mr.JB hesitated with this issue,indicated the appearance of Genesis SEM wouldn’t be changeddue to cost, the same appearance but different model，that wouldconfuse the customer and affect passively to Korea or other regional market.That was a small puzzle.
Soon after，Mr.JB sent a resolution image used for calibrating SEM resolution tothe author. His means was that the author couldn’t obtain thegood result because of worse environment and this image was better，let the authorjudge it again. The author could understand Mr.JB’s means wastrying not to change. But the identified result was not enough obviously.
Mr.JB began to admit the fact of genesis SEM’s resolutiondeficiency，He decided to use Genesis-500 replace Genesis-1000. Mr.JB said thathe would rise in price when he improved the weakness .
The author had no comment to Mr.JB’s rising inprice, good things could have good price, but needed there was no deception. Itwas none of the author’s business if Mr.JB would deceive Korea or other regional customer，but theauthor would never become his accomplice to deceive Chinese.
Admire and torlerate at the outset，deeplyrealize and have to in the end.
Since Long term，Mr.JB and his company cheated the customer via using inferiorproduct pretending to be good one . The author provided the critically factualevidence，here appeal all the victim of Genesis-1000/2000 SEM to sueMr.JB and his company EMCRAFTS, to lodge claims for their bad product and theirdeceptively dishonorable behavior. The author has no right to sue Mr.JB and hiscompany for Genesis-500 resolution is just so-so. But the author’s demo SEM sold by Mr.JB at a high price according to his domestic market price hasn’t beenaccepted so far for the fraud in other unqualified item. The author will accuseMr.JB and his company for the fraud ASAP，safeguardour legitimate interest，firmly hit the unscrupulous fellow like Mr.JB, thereby maintain themarket order in somewhat extent.
However，Mr.JB maybe justify to the charge, He would never have the slightestsense of guilty，perhaps the SEM specifications is worth nothing in his mind, to foolother people and gain filthy lucre is his real ability. Mr.JB has two piece ofduck’s beak, he firmly believe that any problem of his SEM product is thesin of pros and cons. Mr.JB refused to negotiate，claimed anyrequest from the author was illegal and blackmail, threatened if the authorpublish his company’s negative information in public, he will use the friendship in thejudicial system and call the international police and the China police,send the author to the prison with no matter cost，let theauthor can not find any job in the world.
There are many nauseating stories about Mr.JB with his SEM.
To be continued！
5Dr.JB ,theinferior designer of SEM (Scanning Electron Microscope), his outright fraud tothe people all around the world with his inferior Emcrafts SEM is sure indeed，however，It was expected that Dr.JB didn’t admit publicly，and threatened the author or anyone whowant to claim justice with “Korea rod”. Dr.JB sent a mail to the author as follow，which was found in the junk mailbox when the author was doingthe mail backup.
