By Young Bong Kang

I believe privileged to be requested to give a contribution this little foreword for this excellent booklet written by means of my friend, younger Bong Kang. I first met Kang whilst he got here to India in 2007 and joined M/s Ever Electronics (one of the most OEM for the Korean immense, L.G. Electronics) as my junior colleague. From the start, he inspired me together with his professionalism and in-depth wisdom of engaged on the shop-floor, relatively with SMT know-how. To be sincere, i might be merely too chuffed to confess that even though he was once reporting to me, I learnt much from him in regards to the SMT technique! He has a wealthy adventure of 24 years in SMT production, correct from the choice of machines, format of machines, procedure parameters and fabric administration. Kang has positioned all his useful wisdom and knowledge linked to SMT production and provided all its nuances in a truly easy-to-understand layout via this positive publication. After having labored with Sharp and LG Electronics for just about twenty years, i will vouch for the truth that i haven't visible a booklet that's so functional in nature. It makes me discover that if purely I had had a chance to paintings with any such genius in the course of my apprenticeship interval, i'd were miles forward! I strongly suggest this ebook to all who desire to pursue a occupation in Electronics’ production as SMT stands out as the know-how for the long run… This ebook may be a precious consultant to younger engineers in addition to construction managers. furthermore for all those that derive excitement simply from the enjoyment of analyzing and studying, this ebook will certainly supply big delight…

Check the contents with Quality report. Attach a detailed information tag. Follow the FIFO. Make different area of FOR AGING & AFTER AGING. Take the U/F to use on line from AFTER AGING area only. 56 Direction for Use: Dispensing Under-fill: Keep the under-fill at room temperature for 2 to 3 hrs, then load into equipment for dispensing. When dispensing, avoid using patterns that will trap air. (1) Select a dispenser type: a) Hand dispense or time pressure valve – least expensive. b) Auger style valve – acceptable: not giving good repeatability, thus more suitable for large die.

Conveyer ON and when PCB is on sensor, conveyer OFF. Manually need to prepare (arrange) the PCB in magazine. 4 Process Flow: (1) Magazine Loading Process: Down the magazine to unloading position for unloading the empty magazine rack. After un-loading, it will get Off. Lift-up to loading position to load a new magazine with PCB. After loading, it will be OFF. Lift down the magazine to 1st PCB loading position. 5 (2) PCB Loading Position: Screen printer will give signal to load a PCB. Pusher will be ON to push the PCB on conveyer and then get OFF returning the pusher.

For understanding SMT m/c one needs to study PLC control m/c. In SMT manufacturing, maximum scrap comes from Loader and Un-Loader. There are two types of Loader and Un-Loader. 1) Vacuum Loader 2) Magazine Loader 1) Vacuum Loader: Vacuum loader is used for loading only bare PCB (Without any assembly). 1 Process Flow: When Screen printer needs PCB, it gives signal to load the PCB. After loading Conveyer gets OFF. After loading PCB to Screen Printer, Vacuum head down for taking another PCB. Head up with PCB.
