Hi Guys / Gals 🙂 ...
I'm not really much of an electronics DIY. My experience with soldering items on a PCB is quite very basic. But in this project (home automation) that I plan to do, the most critical task is to solder a QFN24 chip into a prototype PCB so that I can start testing the MCU. I know it can be done. I have already seen a lot of videos in You Tube. I'm just daunted whether I can do it myself given the current level of my soldering experience.
Assuming that I get all the proper/quality tools for the task, I still expect to make a number of mistakes along the way. My question is, if I do make a mistake in the soldering, can I re-do it again and again without damaging the chip?

its is better to buy a socket and solder it to the PCB then insert the IC on it.
but, if you wish to solder the IC, check for the IC soldering temperature so you will not damage the internal circuit of the IC. and its better to use a soldering iron with variable temp settings so you can adjust according to the required soldering specifications.

WOW !!! that is really one good news. I did'nt know that you have sockets that small in the market. You really made my day today :-). Thank you so much for the information.

I just check the price of the socket in the internet. It's way out of my budget for this project :-(. No wonder DIYers prefer to solder it in a PCB. I'll take note of what you said with the soldering gun when I buy a new one. Thanks.

NP. and please, post your project here, I am interested on your project 🙂

Ceramic tip at magandang soldering iron yung constant ang heat..
Kung proto typing mas maganda kung ic socket ang kabit mo instead of direct solder sa ic. Para di hazzle mag palit palit ng chip
May arduino proj ako na di natuloy dahil walang oras
Home automation din ang mga component. Like 8ch dpdt relay at lcd pero dahil sobrang busy di ko na mabalikan

How about a breakout board?

The topic (Home Automation - Open Project) we are using was posted by aeonmarky in Home Building and Improvement. I'm not sure who can transfer the thread into this section.

Attached is a photo of the PCB adapter (it's not an IC socket) in which I plan to solder the QFN24 chip - no plans of changing the chip in the adapter. Once soldered, I will use a bread board to test the system, it gives me more flexibility especially with the other parts that I will be using in my testing.

It's not available in the market today. A DIYer made and sold some sort of a breakout board with this chip in 2008. Sad to say, he no longer sells it, and I could no longer find a schematic for the board in the internet 🙁

you can practice using hot air rework station..and a solder in paste form(the easiest way) or you can even do it with basic soldering station with variable temp using a 3mm soldering lead..very interesting project ang WIP nyo sir! kung dito lang kayo malapit samin,i can help you re your soldering problem..
