The optimal height and position to hold your electronics project depends upon a number of factors, including (i) your bench height relative to your seat (if you are sitting); (ii) whether you need to have access to both sides of the PCB at the same time; (iii) the physicals dimensions of the components on your PCB; (iv) the task you need to complete (soldering, taking measurements with a probe, etc); (v) whether peripheral objects, like battery packs or displays, need to be held in addition to the PCB, and (vi) most importantly individual preference, among others. There is no single height at which to hold your work that will allow you to comfortably accomplish every different task what needs to be done.
There are a lot of ways the PCBGRIP system can be configured to provide you comfortable access to your work, while securely holding the PCB and what ever else needs to be held. The following provide an overview of some of the height and position settings that can be accomplished with PCBGRIP.
Height. Depending on what you are soldering, sometimes it is nice to be able to rest your hands on you bench to provide support and to help keep the iron and solder steady. The aluminum extrusions can be easily and quickly detached from the Hinge Assembly by loosening the knurled pivot pin and the knurled index pin. Then the whole rig can be set on your bench. In the following setup we've used some Large Thumb Screws attached to the bottom of the OpenBeam to provide a bit more clearance between the PCB and the bench. The thumb screws also are used to attached the Flat Spring to the OpenBeam. Used like this, the PCB is approximately 20mm from the bench top.
The 10mm stainless steel rod can either be threaded into the M10x1.5 hole in the middle of the Base or inserted into the Rod Holder. When the Hinge Assembly is used without the Rod Holder, the PCB is approximately 30mm from the bench at its lowest position.
When the Rod Holder is used, the PCB is approximately 115mm above the bench at its lowest position.
When the Hinge Assembly is positioned near the top of the 10mm diameter stainless steel rod, the PCB is approximately 350mm from the bench surface.
The Hinge Assembly can be positioned at any spot along the 10mm rod by simply tightening the M8 thumb screw.
Rotated, Twisted, or Turned. While the Hinge Assembly is being used, the work can be rotated 360 degrees around the horizontal axis, tilted in excess of 90 degrees either up or down, or spun around the vertical axis. While the Hinge Assembly is positively indexed at 90 degrees intervals around the horizontal axis, it can be securely locked at any angle with the M8 thumb screw.
The work can be tilted either up or down by removing the the index pin and setting it at the angle you need.
For tilting, positive indexing is possible at 7.5 degree intervals. The 4mm index holes at 15 degrees shown below, mate with one of the 3 holes at 45 degrees in the Hinge Assembly, to provide a positive lock at lots of different tilt angles.
