I have been 'silent' for awhile because I was busy attending E-twinning conference for language teachers, which took place this weekend at our school(from Thursday to Saturday). There were about 65 participants from different European countries (UK, Ireland, Italy, Belgium, Denmark, Sweden, Norway, Spain, Portugal, Bulgaria, Slovakia, the Czech Republic, Estonia, Germany, Poland, France, ...). We enjoyed wonderful workshops and had a lot of FUN. Ewan Macintosh, a cool Scottish presenter, wrote some nice words about our school here.

We are always short of time, always in a hurry... Had you been there, would you have done the same thing? I'm afraid I would.
Seth says most of us probably would and it bothers us. »If your worldview is that music in the subway isn't worth your time, you're not going to notice when the music is better than usual (or when a famous violinist is playing). It doesn't match the story you tell yourself, so you ignore it. We're so overwhelmed by the din of our lives that we've created a worldview that requires us to ignore the outside world, most of the time, even when we suffer because of it.«
Let's not forget to take a deep breath every now and then and simply enjoy the moment. Have a warm, sunny weekend.

The total number of unique phishing reports submitted to Anti-Phishing Working Group in January 2007 was 29,930 – the highest recorded number by the APWG. This is a count of unique phishing email reports received by the APWG from the public, its member organizations and its research partners.

I decided to present our SMT production line at Iskra Avtoelektrika. I work in Electronic BME department. We make DC and AC controllers for various types of forklifts, electrical vehicles, boats and other car industry. We also make electronics controllers for brushless motor. (SMT – surface mount technology)
Our production line is in EPA area. This is Electrostatic discharge Protected Area. In our production line we work with ESDS – ElectroStatic Discharge Sensitive elements (processor, chip, mos-fet and others). So we have specially prepared production area for work. We have also white overall frock with tiny conductor wire in it. When we work with small and very sensitive elements, we have also electrostatic discharge wrist strap which is conected into EBP – Earth Bonding Point.
At the entrance we have test instrument. It is wrist strap and footwear tester, which performs a quick test to assure whether wrist straps and footwear are conductive within acceptable limits.
Before this tester is “material preparing” department. Here we open all non electrostatic discharge packages and separate them. Material with ESDS packages we later import to EPA area where is placed automatic storage.
We work with SMD and discrete electronic components. SMD components we place on the circuits with automatic machines, but discrete components we place manually. I decided to present only automatic part of our production line.
Our production line start with material preparing and after that we have first machine which grease circuit surface with soldering paste. We have a template for each type of controller. Then we have two pick and place SMT machines.
We bought new machine last week which would be used for making VIMEC controllers. This is controller in electrical vehicle for invalids that they can go up stairs. Watch the video presentation of this P&P machine.
After this two pick and place (P&P) machines we have reflow oven. Here soldering paste melts and solder elements with pads on PCB board. After this we have optical control machine calls “AOI”. This machine visually controls whole board and checks if elements are in right position or orientation. It also checks value of elements. If everything is ok, here is another operation. Discrete elements. We put it on the PCB board manually. After this operation we have automatic soldering with wave.
This machine solder all discrete elements. After that operation, we have eye control of controllers. At this operation we soldering wires and other stuff.
Finally here is electrical control. We have simulators of forklifts and we control each controller. At the end we lacquering good controllers with another and the last one automatic machine.
After those operations we have also assembly line where we compose controllers. Finally we have 100% control place where we have forklift and we control if controller work properly. With AC controllers we make also burn test. We charge controllers with current of 300A and wait until controller has 80°C. We watch eventual changes and errors with thermal camera.
At the end we pack controllers into ESD package. That`s all folks!!!
Here's a short video of a really passionate young player – I'm not sure how real it is but looks funny. What do you think of it?
