We have an opportunity to purchase a Yestech YTV-1000 AOI machine. I am looking for opinions on how well they work and how they compare to the newer Yestech B3 AOI systems. We are a high mix, low volume EMS company. We do not currently have any exp

We have been manufacturing a part using bright electrolytic tin as the finish. Our customer has been hand soldering using 63/37. They have recently switched to SN96 and have been experiencing solderability issues. We have sent samples to an outside

I have done this for the Datapaq and it worked well. The SlimKic uses a yellow thermal blanket material. It is called Pyropel. You can get it at McMasterCarr. I think McMasterCarr calls it polyimid foam insulation part number 93015K64 of 3/16 thi

I understand what he means. But has he confirmed that an unusual situation is what is really occurring, or is what happens at every other company happening there? It is very common to have part droppage. Look at all the threads on the subject here.

We recently got a job where (after placing SMT parts) we have to solder LED dot-matrix 8x8 display modules manually on the pcb. Due to the PCB design, it has to be TH type (also, it's the only type available) and soldered manually (or using selective

Loco, Since Dave didn't respond i will. We shouldn't forget that even when using tin/lead solder the boards and components are still lead free. Parts that are not completely wetted by the tin/lead solder still have the potential for tin whiskering a

Hi there: During the past weeks (let's say since beginning of the year) we've been experiencing some issues with shifted components. We verify for position before Reflow oven and the components are Ok, but they observe shifted after reflow. it occurs

Thanks Pete B - great info. I am currently preparing a DOE to address concerns about reflow of componentry on the bottomside of the PCB while in the vapor. Specifically cosmetics and part dropping. Bottom side has no flux, but will be fully reflow

Hello Sid: i don't know where you bought the machine. the central support system is an addition part, it is specially designed to prevent the PCB board from bowing. i know that the wave soldering machine which made before did not include this useful
