PICKit 3 Question

[dt1]

Is there any module/board that allows micro-controllers to be plugged in and programmed with PICKit 3???

Or do I need to make a board each time?

You could try https://www.electro-tech-online.com/custompdfs/2011/09/uniadapter_en.pdf

I saw something similar from microchipDirect:

I can't find anything that supports 44-pin chips such as PIC18F45K20.

Anything with more than 40 pins from microchip is a surface mount device, so can't be plugged into a DIL ZIF.

I find it easiest to programme the PIC once it has been soldered down. 6 holes wired to +ve, -ve, MCLR, ISCP clock and ISCP data, on 0.1" pitch for the pickit2 or pickit3 works fine.

These work well and at a good price.

So, anything with more than 40 pins requires a custom board???

Is there no way to clamp down the chip without soldering it?

You don't say what package type you want TQFP / QFN, but adaptors like this are available, but they're not cheap.

That should do the job.

It looks like a 40 pin PDIP is more cost effective in the long run given the cost of the sockets though.

I agree sockets / adaptors are not cheap, just the socket alone is expensive.

What is wrong with using ICSP ?

If you do not want an ISCP connector on the target PCB there are systems where you just use pads and make the connection with spring loaded pins. Pogo pins might be the name. There are other test clip like setup but they are very expensive.

As folks have mentioned ICSP is the way forward, minimal additional circuitry(if any).
No need to worry about ESD from constant handling of chips when using the zero insertion force sockets!

Explain to me how a ZIF socket makes any difference in terms of ESD.

ZIF don't make any difference in terms of ESD but touching the chips with your statically charged hands may!!

I found this in the read me txt doc for the PICkit3

PICkit 3 Programmer Application supports all devices
supported by the PICkit 3 as of MPLAB 8.60.

hope this helps

Some years ago I build a PCB with various form of ICSP connectors and a socket for each size pic. I doubt I have used it 5 times.

when i very first started out with pics i got it in my head that a ziff was the best way to go, i couldnt get my head round the whole iscp concept. I am so pleased i took on board what everyone on here was telling me and went with a junebug (pickit2 clone) and iscp! deff makes life way easier and quicker. plus i always seem to bend pins taking chips out of sockets so prefer to leave them in once on a board

I've been using ICSP just about as long as I've been using PICs. My first PIC programmer was an Olimex job that programmed via ZIF socket, but it wasn't long before I upgraded to an ICD2 with ICSP. I'm using a PICKit2 now, will be moving on to a PICKit3 when required. The only one advantage I can see with out-of-circuit programming is it eliminates the need to multiplex the PGD and PGC pins with other functions or dedicate those pins entirely. I usually just dedicate them in my circuits. I don't think I've yet run into a situation where I had to use a part with a higher pin count because of it. There's definitely some big advantages to ICSP such as in-circuit debugging and the ease in which you can evaluate changes to your program. Also, the higher pin count parts only come in TQFP or QFN packages and you would need a complex socket to program them out-of-circuit, if it's even practical.
