Hi i got a DPO7254 on my bench, after starting up the unit, it fails with error 315 and 316. My debug logs are pointing to a demux communication problem. my error looks like this: --- Code: ---*************************************** File opened: Sat Jan 07 13:52:30 2023 *************************************** EnablePowerupDiags = 1, puMode=User DiagPowerUpDiagsEnabled = 1 Model: DPO7254 Serial number: B010315, HFD201[0] ID = 0 (0x000000) Scope.exe Version: 5.3.5 Build 22; Sat Jan 07 13:52:41 2023: Executing Powerup diags ...

| mikehank:
I have lots of experience reballing/replacing Demux's on these boards. I had access to a BGA rework machine. I'm not sure I would try a reflow on a lead free board. To hot and and risky. |

today i took the chip off one of the two chips, i just warmed up the heatsink for 1,5 min at just over 400c. and then i could easy take it off the board. i found this on the bottom of the chip a little swallen... very little. ad a close up picture. but how can i find out the swallen part is still ok? diode test between the pads ? if somebody have a Donor board for sale from a DPO7000 series please get in touch with me. (also for just one chip contact me) National Semiconductor: ----------------------Demultiplexer---- VT626ES ADG387C MM9617C 167-0138-00 4673-0 |
| mikehank:
Here is what i would do. Your looking for open pads. Find a grounding pad(should be common with a bunch of pads). Then do a resistance check with pads in the bubbled area. One more thing to consider this bubble may not allow the BGA to sit correctly down. When I have manually pulled these chips is removed the heatsink 1st. Put a small thermocouple under the BGA(it will fit) and keep an eye on the temps as you heat the chip. |
| charlyd:
thanks for your reply i will certain check out the pads and see if it is still worthit. i got myself a rework station. i found a picture on the web of a simulair chip i am looking for. but what is the partnumber ? ADG387C or MM9617C-FBB or ? ( i am a little confused :-// ) who can help me out with a donor chip or board? a internet picture is shown below |
