Regarding your question about buying equipment to vacuum seal the MBBs, according to the IPC/JEDEC standard, "Full air evacuation is not needed or recommended; light air evacuation will reduce the packaging bulk and enhance carton packing. Excessive

Hi, It is very important to follow IPC JEDEC 33 specification for storage and handing of all MSDs. In many instances defects caused by excess moisture in packages is not immediately evident (pcbs may pass final test) but when pcb has been in the fiel

Hi, do you know if your LEDs are moisture sensitive ? And if so what MSL level ? Surprisingly it seems that not all are, but some seem really sensitive. I imagine the differences are down to the plastics used and the LED manufacturing processes. I a

Hi, First check what the Moisture Sensitivity Level of the LEDS is....you may need to ask the LED manufacturer. Once you've established it is moisture sensitive then follow latest version of IPC JEDEC 33 spec. for storage of them and drying them if t

Yes, i agree with you, but for our domestic market, most of big led light manufacturers which can use our machines already purchased our high speed led pnp machines, like FSL, MLS etc, it is necessary for us to explore foreign market, india and brail

thanks for your keen analysis, totally agree with you. If we want to explore foreign market, find one reliable agent is necessary who is professional for led smt machines as you said, after all, the cost to establish branch office is higher , and eve

For typical small sized circle LED panels, you can simply have a PCB routed to said circle... but when lighting fixtures are sizes 2-3 feet+, and a circular, typically how are the LEDs being spread across the radius? I can see flex LED strips being
