So, I got my blank 0.8mm PVC cards on the mail. I’m still unsure why I didn’t order these from Amazon. That takes the French PCBs to the proper 2.4mm thickness. Used one of these wonky Aussie cards to mark out the channels for the eprom legs. Plan was to burn the channels with a soldering iron, make a groove. I actually didn’t burn all the way through. :cheers: Came out pretty good, just ran a pocket knife around the edges to shave off the minor misalignment. Those ---smurfing--- jumpers continue to be an issue. I can’t even figure out what 256Kb eprom would be compatible with this system. Making it impossible to get a good bond in that area. Simplest solution may be cutting the bottom half inch off the pvc cards and leaving the pins exposed. Anyway, since alignment is driven by that top PCB, performance is perfect. I’m giving up on the blue ones. Plan on soaking them in acetone to dissolve the super glue and pop off those EPROMs. :cheers: |

--- Quote from: pbj on December 18, 2023, 01:58:18 pm ---pdco_arcade, PCB Way is rejecting the bottom layer PCB - "Failed reason: Lack of the Silkscreen layer." --- End quote --- Added top & bottom silk layers. Was that a complaint with the original order? PCBWay likes to add the job # into the silk layer to make their job tracking easier. Also rounded the insertion edge corners 0.025". The other card has that radius while these originally had 0.100" radius on the corners. Should make insertion easier. Might also want to file the leading edges a bit to add some taper there. That should help reduce insertion effort too. Also completed the gull wing EPROM mount version. Too much fun. Will post both later today after they get a final review. --- Quote from: pbj on December 18, 2023, 08:40:43 pm ---So, I got my blank 0.8mm PVC cards on the mail.

With the gull wing mount - fab @ 1.6mm & attach one of those blank fillers. Or go for the 2.4mm fab. The attached files pcb_1_B.png & pcb_2_B.png are more of less the original version with round corners, text in copper and silks for the 'blank pcb. While pcb_1_wings.png & pcb_2_wings.png show the surface mount idea. Got fingers crossed all this is correct. |

Sir, I await your pcb file revisions like things I haven’t anticipated in at least 20 years. Meanwhile, playing around with the garbage I have on hand. PS - Malenko had some beautiful inserts printed intended for 10.4mm jewel cases. I will begin rotating my loose legitimate HuCards to something more fitting. I can’t believe I’m buying CD cases in 2023… |

Whew- Here are the modified PCB - Have slightly rounded corners at insertion end, have extra pads for surface mount of the EPROM, have 2 new holes for PCB alignment help, modified the insertion fingers & via's to support gold plating if wanted. Hope it all is correct. Editing gerber files is a tedious process. So much easier working with a PCB in the CAD tool. Give it all a good review before ordering and go the least expensive route initially. |
