Can I cut an IC?

As far as I understand, the die of a DIP package is located at the center and the rest is just the lead frame. Given that I have unused pins, can I cut the top part of this microcontroller (ATmega16/32)? Will it still function afterwards? Edit:…

Are DIP sockets against overheating worth the cost?

Sockets allow easy replacement of a device and eliminates the risk of damage from overheating during soldering. [Wikipedia] I personally never (ever) replace these ICs. For programming microcontrollers (as a hobbyist) I use a dedicated pin header.…

How to cool down DIP devices?

I have AD811 in my application that works just fine but as it is working in +/-15 v supply at around 14.5 mA, it's power is around one third of watts. It is hot when touched. I checked if this is a malfunction in this website and contacted Analog…

What kind of damage could a soldering iron do to a component?

As a follow-up to this question, what kind of damage could a soldering iron do to an IC or other component if left on it for too long at too high a temperature? ESD damage can be subtle, for instance. Is overheating damage usually obvious/complete…

How to remove DIP ICs from breadboard?

I am new with electronics and I have some issues removing DIP ICs from breadboard after testing something with them. I end up bending their legs if I pull them with bare fingers or pliers. Is there some recommended way to pull them up nicely?

Why are 10-pin DIP integrated circuits so uncommon?

This is a tangential thought from this answer, specifically the line "There are 10 and 12 pin DIPs". After some searching around, I finally located only one 10-pin DIP part: NTE1450, 5 Watt audio power amplifier. The part is evidently obsolete, and…

How do you identify Pin 1 based off these pictures?

This is a test question in a study book about electronics. I cannot find the answer and have no idea which picture identifies a pin. Am I missing something? Any help on the right answer along with why that answer is correct would be helpful.

Why are VCC and GND on diagonally opposite pins?

I noticed that most of ICs (DIP or SOP) have VCC and GND pins on diagonally opposite pins. Decoupling capacitors must be connected with shortest traces. Placing power pins in the corners makes the traces (inside the chip and outside on PCB) longest…

Question about assembly with DIP packages

I'm sending a board for assembly with a through-hole DIP-8 package with a standard horizontal lead spacing of 7.62mm. However, at their ends the pins are wide with a pin spacing of ~8.47mm. Should I modify my footprint to accommodate this wider…

Prototyping with SMD components?

In response to the answers here: How much longer should we expect DIP (or DIL) Packaging to be around? If DIPs are phasing out, how would one proto their boards quickly and cheaply? Does this mean we have to all start learning to build surface mount…

Why aren't components in DIP package shipped with straight pins?

I've noticed that all DIP packaged devices have pins which are at an angle other than \$90^{\circ}\$ and need to be bent so that the angle is right for insertion into holes on the PCB or wherever. Is there any reason other than tradition for that? I…

What's the benefit of not soldering NC pins compared to soldering them to a disconnected pad?

I've been looking at my scope's power supply board and I noticed that R7731A "Burst Triple Mode PWM Flyback Controller" in DIP has two NC pins which are not connected to absolutely anything. They've been inserted into holes, but there are no…

DIP to SOIC-8 Adapter

I'm just getting round to a project that calls for a SOIC8 IC to be surfaced mounted on the PCB. The part it calls for is nowhere to be found (the backorder is several months at least!). I can, however, source a DIP8 version of the part. So, to…

Do IC's in DIP sockets require an extraction tool?

Am I correct in that the IC extraction is used to extract an IC from a DIP socket for swap/extraction in a safe manner? Or is it used for something else? I doubt I will need this behaviour, however if I damage the socket it is worth a few dollars to…
