Which is the best way to allow the 1200mm length LED tubes easily to be loaded into and unloaded from the LED( SMT) process line? The difficulties to such kind of longer length (1200mm) LED tubes are not easy to find a suitable magazine for it. As we know in the SMT boards handling machines market, the magazine standard is fixed and also the maximum. common magazine size is 535x530x570mm (L*W*H) for the available maximum. PCB size 535x460mm ( L*W). It comes out that there is no standard magazine for the LED tubes ( 1200mm) lengths.
The reasons for the appearance of the "tin bead" of the SMT soldering surface and the preventive control method
In the SMT soldering process, we consider that the potential reason to cause the “tin bead” of soldering point are highly possibility in the Reflow oven temperature setting, SMT Reflow soldering time, solder paste quality, solder paste printing thickness, and screen quality, as well as the mounter pressure. So finding out the root the problem of “ tin bead” and do the anticipate control to avoid the “ tin bead” in your PCB SMT process.
With the development of the electronics industry, the lead-free technology (lead-free reflow soldering) becomes more and more popular among users. However, in the global market there are so many brands of lead free reflow oven, finally we find it’s not easy for us to make a decision on a good performance reflow oven with the affordable price. Don’t worry! Now Here 7 tips are special for you!
