Diference between PK3 and production programmer

[HenrikOlsson]

Hi,
Of course there can be no difference in "quality" of actually programming the part, either it gets the device programmed or it doesn't.
I guess what they mean is that the hardware and software may not be suited for automated programming or gang-programming in a "real" production environment doing thousands and thousands of "cycles" per day. If you're doing "bench production" I'm sure it works just fine. After all, the PTG-function is quite nice for repetitive flashing of the same firmware (it's just too bad that the PK can't be powered from the target when using it).

Now that I come to think more about it, the PK has this cheap pin head connector, that I suppose it may have a shorter life that other types of connections.

On my Elnec, I use the ISP connector with a spring type needles to get in contact with PCB pads of the ICSP connections. These needles have very sharp ends and make very good contact with the pcb. And they are easy to change with spares. You just pull them out and replace with new ones.

Unfortunately I do not know the english term to help you find them. I got them from the local market.

Also made an adapter and use this needles with PK2, 3 or ICD3.

They're usually called Pogo-pins.

Thnaks Henrik. It was impossible to find this! Strange word...

Thanks...
But microchip local distributor try to convince me that data in PIC flash stay valid only about year or so when programmed with PK. But when is programmed with with "real production programmer" it stays for decades
Programing header is very easy to change, so for me that isn't problem.

Hey, come on. Don't tell me that you believe these crap?

As Henrik posted, either it programmed or did not programmed correctly. What is this ... volatility of the code?

Yeah, OK, code is like alchohol. It just evaporates after a while...

I don't believe... I have pic's that is running for years. I tried to point that to him, but...
I was just wondering what is your opinion on that.

Nah, I think it's the conductive pathways within the PIC that run out of electrons.
