Very interesting, thanks! I will order some of these chips but I think I will not be able to solder them correctly. There are some videos on youtube showing how to solder QFN packages using tons of flux and hot air... -- You received this message because you are subscribed to the Google

[neonixie-l] Re: HV5523/HV5623

I've used a heat gun to remove surface mount parts, but never to install one. I removed a device that looks like the aforementioned QFN, and the metal die-paddle on the bottom took a lot of heat to remove the part. I toasted the PCB because there was no heat-control; the PCB delaminated and

I was surprised that the data sheet didn't give more thermal information relating to the pad - the chip, under load, dissipates up to 3.4W in a very small package, so the pad is important. It'd have to be reflow for it to work - that along with appropriate board design to carry the heat

[neonixie-l] Obtaining 2 digit Panaplex displays

Hey, I've been looking for some 2 digit Panaplex displays. As these are for something I want to design the exact model is unimportant. I would prefer the smaller displays, SP-332/336/732/732 but the SP-352/356/752/756 might also work. I have looked at alternatives like the SP-151 which might

[neonixie-l] Re: Babcock display SP-431-001

I am willing to help you out with this. The seller does not say how big the display is, so might you know how big the package may be? I will send you a PM shortly. Ron On Saturday, October 28, 2017 at 9:24:34 AM UTC-4, kosbo.com wrote: > > Hi All, > > On ebay I was looking for this display

If you can't find a closer supplier, I have some spare NOS SP-336s that I can let go. I'd have to ship from the US. If interested, contact me off list with the quantities you are looking for. carl Henry Carl Ott N2RVQ
