New drop-in solution for port and battery connector

We know that many of you are put off by the difficulty of changing the battery connectors, due to the fact that you need to perform several steps:

  • Buy the flex circuit (that's the easy way)
  • Disassemble your calculator (easy too)
  • Peel the corroded circuit off
  • cut the rivet heads and clean the plastic from dirt and rust
  • Pre-fold the flex circuit to suit the plastic shape
  • Carefully adhere the circuit to the plastic shape - usually the most difficult and nerve-breaking part
  • glue the borders with a better, more resistant adhesive
  • Let the glue dry and finally place the assembly on the back side of the case
  • Assemble the calculator and pray for the whole to work.

For some time, and taking profit of the experience and steady hand of Ignacio Sánchez, we have offered preassembled kits: we took the plastic piece of a non-working calculator and performed the above steps - so that you did not have to. These parts sold immediately. The problem with it was that we were limited to the number of non-working calculators we could find - and that dried up very soon.

So we set up to create the plastic piece ourselves. We had to get familiar with the new CAD design programs - having used Autocad 25 years ago, there was a lot to be refreshed! Then we carefully measured the piece with a caliper, and once finished with the drawing, we sent it to a 3D printer company. Now we've finished the testing phase and are ready to deliver the first units.

IMG_3850This process has given us the chance to improve on the original (with softer bends and more extended adherence area), but also to create an alternate version (which can be seen on the left). If you have repaired several calculators, you surely have received one with the back side broken: the support for the screws in the back side has cracked. There is no repairing it with any kind of glue, as you know. Well, one of the versions of the battery assembly has a wide flat area, so that it can be glued to the back side and solve the problem with the broken calculator backs! The head of the screw will rest on the flat side of the piece, and the back side of the calculator is held in place due to the force of the glue over a wide area (not just slim borders as would be the case with the original piece)
