After several weeks of hard work we can now say that the first preproduction stage has been accomplished!
It hasn't been easy and we found some problems in
the PCB (printed circuit boards) and we had to reject the first panels
because of the low quality.
This issue has delayed us
considerably, but we've already detected and corrected the problems and
everything's going on wheels now.
All this matter has showed us how important is to follow every
preproduction step to assure that we meet all the quality criteria,
although the deadlines get longer.
understand that you missed some more communication from us, but we
wanted to solve all this issues first so we can also communicate the
Now, issues solved, and almost living in the
factory, we'd like to show you how the production process will be, and
we've taken some video footage to make a video:
As you can see in the video, it shows all the steps during the electronics production:
Step 1: Solder paste printing process. In this step a dense soldering
paste is applied on the PCBs through a stencil over the components pads.
This paste is the material which will solder the components to the PCB.
- Step 2: Components Pick & Place process. This
is the high speed, high precision placing of all the electronic
components. A computer-aided machine places all the components on their
right position and orientation, all done automatically and really fast!
This machine uses CNC technology and intelligent vision to find the
place and rotate the components if necessary. The components reels used
to feed this machine can also be seen.
- Step 3: Reflow Soldering Process. Just after the
Pick & Place process, the PCB panels go through a reflow oven which
melts the solder paste and solders the components to the PCB.
- Step 4: Visual Quality control to check all the solderings look
good and there are not shortcircuits or unsoldered pads, specially along
the smallest components which are the most critical ones.
- Step 5: X-ray Zoom Quality control. This machine is amazing! We'll mainly use it during this preproduction stage and it allows us to see all the
hidden solderings under the components to check that all the process
will run smooth during mass production.
And that's it! The electronic board is now ready to
receive it's battery and LED matrix and to be placed into the plastic
We also want to include some
pictures of the components reels ready for production, as well as the
front RGB LED matrices that also arrived at the assembly factory. As you
can see, the process is going rather slow, but we've overcome the most
critical stages of preproduction and we'll start mas production soon.
Lots of LEDs!
Preproduction Assembled 1
Preproduction Assembled 2
Just as a comment,
during the whole production process both all the components used and all
the processes involved comply with the RoHS directive which restricts
the use of hazardous substances such as lead, mercury or cadmium.
So, if everything goes as expected from now on, we'll start mass
production in a very short time and we hope the first L8s will see the
light by beginning of April.
We really hope all you are as excited as we are, because now we're very near to see the first final L8s ready to be shipped!!
