Multipilot32 Board Quality????

I just got my shiny new Multipilot32 and IMU boards from Italy today.  I must say I was quite disappointed with the quality of these production boards as shipped to me.  Some of the issues are as outlined below:

 

1. There is no way that solder paste was used on the surface mount parts as they should not have balls of solder on the caps/resisters.

2. There is WAY too much resin flux on the board.  These production level boards should have been washed to remove the flux from the chips.  Flux can actually damage the boards over time.

3. The biggest issue I have is that there are wire 'fixes' on BOTH sides of the board to correct mistakes with the board layout.  These fixes are fine for prototype work (we all do it), but if there is more than one on a board it really should have been respun before SELLING them to the public as a production board.  If the board was sold to me as a prototype grade board I would have had expectations completely different than I did thinking they were professionally made quality boards.

Having said that, I like the work that is being done and look forward to using the boards and contributing to the project.  I hope both my new boards were fully tested and working properly.

  • Hi Matt,

    i'm sorry . At the moment the MP32 v 1.0 that is only available have that two wire to support the external resonator. In the first design the mp32 supported only internal RC so we don't need an external crystal . The limit of internal resonator is 65 mhz . After doing the production of PCB we decide to use also external resonator so we patch the board because the hardware remap don't work .

    In the next revision of board that will be available in October we solve on new pcb this problem and support different kind of micro STM32F103 and STM32F205.

    For the IMU we doing a small batch externally and we found that the quality of production is not so good so after saw what happen on Oilpan that had a lot of board where some axis on gyro or on acc don't work we decide for every board to manually solder every sensor component and check every board before to send it to customers. 

    So at the moment this project had a small quantity of production so we can test each board we produce.

    So for upgrade the board to gps is possible that you upgrade it .

    Here you can found at the end of post the two schematics one for mp32 and other for VRIMU.

      Very Good....I will go over the schematic and contact with questions.  I am glad to see that at least you are testing all the in-house built boards.  I do a lot of prototype circuit boards for work as well and I know how it goes.  What else will be different with the October version of boards?

  • I just looked back through all of the photos on the website and there are a handful that actually show boards with wires so I must have missed it when looking originally.  I sure hope it all works okay.

     

    I didnt seem to get the GPS option with mine......is it possible to order the additional components and solder them on myself?
