Mintyboost v3 not charging

Post by Dannyven »

Greetings,

Received a MintyBoost v3 for Christmas and completed assembly today. Prior to installing the USB my multimeter read 5 volts across the 1 and 4 pin connections. After installing the USB and connecting to my iPhone 5s it would not charge. Picture of my PCB submitted for review by the experts. Its not perfect but I see no obvious shorts or bad connections. As shown the USB 2/3 pins are soldered as an attempt to fix the issue. Any advice or help is greatly be appreciated.

Thanks,
Danny V

There are a couple of joints there that have not flowed fully onto the solder pads. An one or two look a little rough an could be 'cold' joints. On this project, good soldering is important in order to reliably conduct the high current needed to charge a phone.

Take a look at this guide for tips on identifying and fixing common soldering problems. http://learn.adafruit.com/adafruit-guid ... n-problems

Also make sure you are using a fresh set of batteries designed for high-drain applications.

I am having a similar problem with my v3 minty boost, after I put it together and connected a battery I am getting a charge into the mintyBoost, but when I try to charge a phone or test the charge coming out of the USB I get nothing. It could be the soldering or a component went bad. If any of you guys notice anything, let me know. Here are some pictures I took. Thanks

It may be just the lighting, but one of the pins on the boost chip looks like it is not completely soldered. Check this guide for tips on fixing common soldering problems.
