Re: k&s 1470 Wire bonding reconstruction

 

Hello,

I was also interested in getting a K&S wire bonding machine for the same
purpose to fix the HP YIGs but the ones that I found were missing parts.

I was looking for any manuals that showed the parts list so I can try to
identify exactly the missing parts but I found it impossible to find any
K&S manuals.

I am interested if anyone has user manuals and especially service
manuals for the 412x and 452x series of wire bonding machines from K&S.

One of the parts that the ones I found was missing was the heated
working table and I found exactly zero on eBay.

Let us know how is your project developing. I am more than interested in
updates.

Regards,
Razvan

No problem, Massimo, I am happy to help out.? I did get a response from one of my contacts to reach out to another person who may be able to find you a service manual.? I need to look up that person;
?probably won't have time until tomorrow evening.? ? Jim

Hi Don, thank you for your reply. I'm not very versed at all in the 8566B; I recently picked this unit up locally for a very good price, but was not able to test the 2-22 GHz section until I got it home. So I'm coming into this was no experience on the 8566. I appreciate your suggestions and will give them a try. 6 GHz is the highest source I have to test with at the moment.?

I'll be sure to post my findings, though it might be a day or two until I can get to it. I also have a thread on the EEV blog that includes everything I've done up until this point.

I have not found the part numbers in any cross-reference lists and I have been unable to identify the parts by their markings.

Re: HP attenuator 08662-60082

 

I thought I'd follow up on my own post. I made a suitable PCB layout in 0.6mm FR4 and had some PCBs assembled with ENIG finish.? They use minicircuits LAT series attenuators (for the first section 3 LAT-20s since the ratios are 20dB and 40dB).



(original HP can be seen here after most of the gold had fallen off )

The gold contacts needed some cleaning with deoxit gold (I guess the plating is very thin and the green corrosion comes through).? The ENIG gold is a lot thinner than that on the original HP board and I put a 0.05mm shim underneath the PCB to compensate.? The result on the VNA seems reasonable over 10MHz to 1.25GHz.? I used a board with ground plane. Still not sure this was the best choice, but it was the one most familiar to me.

Now I have to figure out how to update the leveling EPROM, assuming I can measure the attenuators sufficiently accurately on the VNA. PCB layout is here if anyone is interested ?).? I don't suppose anyone has any documentation?

Re: 8566B - Low signal on 2-22 GHz band

 

Pete, How versed are you with the operation of the 8566B?
Try this first, there is a key on the RF section (it might be a shifted key) call PSP. This is preselector peaking. Do this at 2.6 GHz or 3 GHz, then at 6GHz (this is close to the band edges of the 1st preselected band), if you can see a signal after that, that is much higher in amplitude then you may have an alignment problem. Look up how you do manual preselector peaking and for each of the upper frequency bands (2-6.2GHz, 5.8-12.5GHz, 12.5-18.6GHz, 18.6-22GHz). You should check the low, middle, and high end of each preselected band. Ideally the DAC numbers should all be 32 +/- 10 (range is 0-63), anything outside of this range indicates a frequency realignment may be needed. If you still cannot see a signal that is close to the correct amplitude then you may have a component failure in the preselected RF/uWave path.
Pleas post your findings so that we can point you in the right direction .

Re: Interfacing the HP3490A with AR488

 

Hi Chuck and Dave,

Thank you for your responses. I'm quite a newbie to HP-IB, and I'm learning !

At this time I am able to use the AR488 successfully with a 34401A and a 3457A, in both cases sending instruction codes (to select DCV, ohms, ACV, ranges, etc ...) and receiving measurement results. So far so good.

I did some further reading of the 3490A manual, and table 3-6 on page 3-9 would imply that the 3490A must use two different addresses. For example, it is shipped from the factory with the jumper configuration shown in figure 3-7. This sets an HP-IB address of 66 octal (54 decimal) which is for listening. But this same jumper configuration sets the talk address to 126 octal (86 decimal), which I understand is the address from which the 3490A will talk from, when sending results.

This dual-addressing mode is somewhat puzzling ...

Could anyone with experience of the 3490A on the HP-IB confirm my understanding ?

For me the next step would then be to use this "uncommon" addressing scheme with the AR488.

Thanks to all,

Joel
Re: 8753C Sampler Replacement?

 

I have replaced bad samplers in the past (on HP8753ES instruments).? And yes, when you replace a sampler or a port coupler you do have to run through a calibration proceedure to get everything just right.? The calibration proceedure isn't very intense and can be run in about 30 minutes, but it does require a few insturments (power meters, special cables, etc) to do it.? The power meter requirements vary depending on whether you have a 0-3 GHz or the 6 GHz option, but that might be only on "D" and up that you have to worry about this.

But if you fail to do the calibration then all that really happens is that your baseline response prior to doing a cal is a bit off.? Once you run through a normal 50 ohm cal (which of course you would do prior to any measurement), you are going to get pretty decent results.? So, long story short if you can do the recalibration, great - that's recommended.? If you can't, not ideal, but as long as you do a proper cal prior to making measurements you should be fine.

Depending on where you are at,? one of us might be able to loan you the equiptment needed to do a cal.? It's really not that extensive.
Re: HP 3325

 

As others have said, linear supply pass transistors usually aren't super critical and you can frequently figure out something to replace them with that will be at least as good.? I also look at manuals for similar equipment if I get stuck, as you suggest.
