Please recommend a PCB hold diameter for LTE-302

Thanks for reaching out! Let me contact our engineers about it and we will get back to you shortly for more updates.

According to the manufacturer's specifications, the recommended hole diameter for LTE-302 is 0.86 mm. However, the current design uses a drill size of 0.8 mm, which may be causing the soldering issue. It's also important to note that the part's lead size is 0.5 mm square.

We suggest increasing the drill size to 0.86 mm to resolve the issue.

Thank you!
