PCB assembly

Jason Zhu

Product Manager @ WELLER

Hi Jason,

 

Thank you for the file, I’m glad you’ve made such a progress.

The pcb looks very good to me – you’ve took all the proven design experience from the earlier boards.

I’ve found small details though:

“Hi Carl,
Me too, I appreciate your trust! And you give me a great help (for example with the project Microchip which without you could not be a success!) And I feel the whole heart that has been put by everyone in the work that I receive. This is very important for me because I work in the same way. And I have trouble seeing this world that is content to see humans as objects.
Thank you very much!

“Hi Jason and Kira,
Thanks for the last couple days. You took a lot of time to drive me around and get stuff done. I like the way you guys work and get things done – it is a lot like how I do things. Working in the hotel room, I have done that at so many trade shows. Good times. But thanks. And you sure have great guys at your factory. That Xie guy is good stuff. Look forward to our next meeting.

Hope you had a great holiday! This is a project for an old client, we previously manufactured their boards at another factory, and because we are very happy with your quality and service, we would like to move this to you.

“Hi Tina,
All three boards have now been tested at full current. 30 amps out at 20V, driven by a 12V battery (that dropped below 12V during the test) at just over 60 amps. Everything seems to be working as hoped for. We will mount them is a metal box and use thermal potting as heat sink on the MOSFETs while the load is high. At 15 amps output, it requires no cooling. A success! The break-out boards are also very nice. Well made… Thanks for your help in getting these prototype boards made. We will definitely be back!!!

“Hi Tian,
The AoA PCBs from DHL were scheduled to arrive Monday, but came early on Friday (today).
So far, I only assembled the small PCB into the 3D-printed bezel with the momentary switch and the LED. The bezel board (small piece) fits PERFECTLY. See the attached. The 2 pressure sensors that are still on backorder are required to test the main boards. I just wanted to tell you that your work is superb! Amazing! Thanks so much again for helping with the anomaly (J2 & J4). Dave P.S. I don’t remember if I explained what it is. It is a safety device that should help to eliminate the main cause of aircraft crashes. The main board calculates the angle of attack of a flying airplane and shows the pilot how close he/she is to stalling the aircraft. The small bezel PCB with the 10-segment LED goes on the aircraft’s instrument panel. As the aircraft slows down to land, the LED shows how close the aircraft is to a stall by progressively turning on more LEDs.

“Dear Jason,
Good Afternoon !! The 5 PCS PCB project we did is working okay. I have also assembled that PCB with components and its working well. Just to make you remember, see the attached PCB’s that you had send me. Since this is working well, can you send me following files: – Gerber files – PCB design files I am suppose to give you order as well, but due to some reason its getting delayed (some of IC’s have got obsolete). But I will surely get in touch with you and Bella very soon for our next order.
Thanks,
Rohit. From India

thank you very much for the Altium file. I did a design rule check in Altium and I have no errors. This is exactly what I wanted. If we have more projects of this kind in the future, I will contact you again.
