The Electronics Area

Area Warden - Brad Walsh --Brad Walsh (talk) 19:01, 12 August 2018 (EDT)

The electronics area exists on the two desk areas in the portion of the two pallet racks that are closest to the window in the Annex. It is divided roughly into an assembly area (closest to the window) and a testing area (closest to the door). There is an anti-static mat down on top of both desks.

Items on loan to the hive are parenthetically noted. Items owned by the hive are noted 'hive13'. If not noted, it is probably owned by Hive13, but please ask if uncertain.

Please keep table tops clear and clean.

Please do not borrow individual hand tools, take a tray if working on repairs, etc away from electronics area. This keeps the tools together and prevents small tools from disappearing all over the space.

Test equipment tested and in spec unless otherwise noted as of 5/2015 - --Lorin Parker (talk) 19:01, 17 July 2015 (EDT)

Soldering Tools in the Area

• Weller WES50 Temperature control soldering iron (cjdavis) - located on top of workbench, plugged in
• Xytronic 968 Combination temperature control soldering iron / vacuum desoldering iron station (daveb) - located on top of workbench, plugged in
• Soldering tweezers (player2) ( link)
• Leaded Rosin core solder, several rolls (hive13) - located on shelf of soldering bench
• Lead free solder, one or two rolls (hive13) - located on shelf of soldering bench
• Three tool trays containing tweezers, hemostats, wire strippers, and other hand tools. IMPORTANT: When using these tools away from the primary electronics bench, please take the entire tray so electronics tools stay together and get returned. "Grab a tray, not a tool!".
• 2x4 stand that says "SMT ONLY" with solder tip cleaner, 28AWG No-clean solder for SMT work, 28 AWG water clean up solder for SMT work, and 21 AWG water clean up solder for SMT work. Please note: this solder is expensive (~$50 / lb - roll) so do not use it for through-hole stuff. (hive13) - located on top of workbench by soldering irons.
• Flux pens, liquid flux, solder paste. In mini fridge below bench. Make sure this fridge stays on, these items must be stored cold.
• Solder Paste dispenser - this is not actively set up but it is a matter of connecting attachments and going to town. (hive13) - located in labeled box on shelf above soldering bench.
• Reflow oven - stainless steel toaster oven with homebrew PID temperature controller (hive13)
• Stereo Microscope (jon) - assembly area, comes and goes
• Wire, clips, leads, etc - hanging on wall.
• Large Panavise circuit board holder (LorinP)
• Nifty flexible 3rd hand (Jon)
• Traditional 3rd hand
• Magnifier lamps, headbands, lenses.
• Wave solder machine (daveb) - no longer at hive13. If you require the use of it, contact daveb.

Testing tools we have

Projects

• PCB and Stencil Etching setup (LorinP) - Heated Bubbler Tank, exposure/development equipment and supplies. Update (7/2015)- Almost ready. Lorin needs to mix and prepare chemicals and set up venting.
• Toaster Oven reflow oven for solder paste / surface mount soldering. Works (7/2015), see project pages for instructions.
• Refine SMT assembly methods - Solder stencil chemical etching possible with Al and copper sulphate etchant (do not use FeCl or CuCl etchant).

Electronic components

• There is a fairly large selection of wire on racks by the window ranging from about 10 AWG to 24 AWG.

• Many Asst. components - ask area warden for details.

Consumable Supplies

The main consumable supplies in the electronics area are solder and soldering supplies. For many of these things, other brands/part numbers may work ok. These part numbers are for the exact replacement of what has been used successfully at the Hive:

• The Flux pen for hand SMT soldering Kester 2331-zx (may be discontinued)
• 21 AWG Water clean solder - Kester 24-6337-6403 $40/lb-roll (Digikey: KE1300-ND)
• 28 AWG Water clean solder - Kester 24-6337-6422 $70/lb-roll (Digikey: KE1303-ND)
• 28 AWG No-Clean solder - Kester 4-6337-8806 $60/lb-roll (Digikey: KE1405-ND) (Prices updated 1-2019)

Alphametals rosin core solder - (may be discontinued but daveb has about 20 rolls of it so if the hive runs low, let him know)
