K-Pak Production Update: PCB Fabrication
We are pleased to say that the first 2,000 sets of PCB’s (Printed circuit boards) have been manufactured at our CM’s facility in Northern California! The PCB manufacturing is comprised of several steps. The first step is what is called the “fabrication” of the PCB, which means that the bare PCB (without components) needs to me made first. The PCB itself is comprised of many layers of FR4 (a glass fiber epoxy laminate) and copper. They are intertwined with “vias” or pathways so that one copper layer can be connected to another where necessary. Once the bare boards are made, they are tested, then sent to the next stage for “fabrication”. The fabrication process is mostly automated, where high speed “pick & place” machines put the various components on the PCB.
Once the PCB’s have the components placed, they move into a “reflow oven” which melts the solder and fuses them with the copper contacts on the bare PCB. Afterwards they are inspected, and any touch-up work is done, as well as the placement of any odd sized or other components are hand soldered.
