Welcome to Boardsort™ - Learn - Sell - Profit -

Normally I'd consider this resistors but these were labled "ICxxx" in the silkscreen, and are in the placement onboard where typical DIP packages were on some of the other iterations.

Edit: not very clear in pic, the marking on the black ones is "OE545t 7y2" my connection to the force is not great and returned no relevant info

I don’t have the part in my list. What was the board and do you have a photo of the placement? My guess is it may actually be a controller in a sip package

Unless it’s from the pictured board. Such as where IC212 is located?
If so I’m further sold it’s an IC.

Yep that's the placement in pic, these were from early "digital" rc controllers

Dug through the bins to find an un depopulated one and found some other boards bearing similar, one has silkscreen "I" mark, the other has no labels

Yep, fairly sure they’re SIP ICs.
The only place I commonly see them is in A/V equipment. But I’ve heard they are big in military equipment too and Aerospace. Among others.

It takes up less space and dissipates heat better than an in-capped DIP IC package. But there are some major trade offs to them.

I’m also going to head at the origin being in house or a custom short run production since I can’t match up the ID number.

Woohoo I found it.
Buried in a copy of the microelectronics journal.
In a parts list advert. Lol. No idea what it is still but it’s part of the r200 series of chips. Nearly all of which are Microcontrollers.

Think we’ll say IC for these here.

You found em too!

These were the ICs I was talking about a few months ago plus a couple more that are labeled, I, IC, or U. I just wasn't sure because the solder only one side and are also not BGA style. I'll send a picture later this afternoon to show you finally.

As for pure facts I have a fairly strong history in a minor but significant section of technology. Outside of that is probably what I would describe as 75% experience and 25% guessing.
And I’m not ashamed to admit that at all.
My database, now part of both Google Books and Internet Archive, is one of the largest collections of useless junk scans ever made. From journals and thesis to magazine and catalogs.

My own history and my back references say good for IC.
Am I positive? Not here, NO. But I’m 90% sure.
And as I posted in the rules sticky (you did all read that, right!?!!!!!??), when I say I stand by a grade I mean it! My database is 100% accurate. It took 1.5 decades of spellcheck on OCR to be sure it was.
I’m sold.
[b] I stand by this![/b]Chris’s will pay you IC rate it I will personally cover any difference.

SIP (single inline pin) was NEVER a popular design.
ZIP (zig zag) mitigated some of the issues. But the reality was cross talk hampered the ability and leakage killed certifications in many countries
The package design had its uses even to this day but generally, as noted above, the downsides kept it regulated, generally and legally, to very specific case conditions.

I agree with Lostinlodos, those sure look like single inline IC's to me as well, good job!

Normally, in general terms I define an IC chip as having two or more sides containing 3 or more pins each side.

That "definition" is not from a technical standpoint, as we all can see from this thread, ICs come in many shapes, sizes and configurations. The description was more of a technique of being able to visually separate ICs from the other components a scrapper might come across. This qualifies 99% of the IC population out there and it makes it easy to explain, especially to folks who are new at this.

So yes, toss that into your IC bucket, no worries!

Just remember to always remove the DALLAS batteries, they look like ICs but they are evil devices. Not only do they contaminate our IC loads, but they also destroy vintage hardware when they fail and corrode or explode, but that is a different topic all together.
