TQFP adapter case

thingiverse

The primary goal of this case is to minimize accidental shorts, provide protection for the pins, and offer a straightforward method for mounting the PCB. The PCB boards are designed to snap into place within the case, resulting in two mounting holes. This solution was developed specifically for some PCB adapter boards I acquired from eBay a while back (33.91mmx41.40mm). These boards enable 0.8mm TQFP (32 to 64 pin) on one side and 0.5mm TQFP (32-100 pin) on the other. Searching eBay for tqfp adapter yields numerous results, including a specific product: https://www.ebay.ca/itm/2pcs-QFP-TQFP-LQFP-FQFP-32-44-64-80-100-to-DIP-Adapter-PCB-Board-Converter/141975820325?hash=item210e6b1825:g:KEIAAOxyPKNTmAlU:rk:1:pf:0 These adapters have proven to be highly effective for my collection of atmel atmegas 128a microcontrollers. The design was created using freecad, and both freecad and STL files are included for your convenience. Print Settings: Every printer and material combination requires unique settings. The images provided showcase my initial attempt. Since I consider this a tool rather than a decorative item, I print quickly, loosely, and with an imperfect finish (100mm/s, 0.4mm nozzle, 0.2mm height, 115% feed rate, etc.). You can achieve better results. Note: The pins and pads on the bottom are also connected to those on the top. A hole was left at the bottom for easy addition of a repair wire or resistor if needed. I'm eager to hear about people's successes and failures with this design, as I've already observed differences between the anet a8 and creality cr20 (for better and worse).
