2015年6月23日 · Under TI VSSOP-8 I found at least two different package widths. The pcb pad layout dimensions and ic package dimensions are towards the end of the TI datasheets that I have seen. Use the one for the device and figure some way to keep them clearly denoted in your CAD libraries to avoid getting bitten with "throwing stars" for pcbs.

2024年6月10日 · I just recently discovered (the hard way...) that VSSOP-8 is an ambiguous IC package name. Some manufacturers use this name to describe a 0.65mm pitch device, whereas others use VSSOP-8 to describe a narrower 0.5mm pitch device. The answer in the above referenced that question says to lookup IPC-7351B, rather than use the short name.

2021年2月15日 · I recently took on a personal project that requires a vssop-8 chip:ADC081C021. In order to help me solder the pins on the pcb, I ordered a vssop-8 stencil online. But when it arrived, I found the pitches were different. The stencil is supposed to have a .5 mm pitch while the adc has a .65 mm pitch.

2018年3月30日 · The component is supposed to be TCA9517DGKR, a level-shifting I2C bus repeater from Texas Instruments. I got these soldered from a turn-key Chinese fab. The top markings are TI43 (Or T143?) first l...

2022年2月10日 · Are any of the SMD IC package names unambiguous? Is there a longer, more official way to name these device packages to eliminate ambiguity (e.g., VSSOP-8,p0.5 for a 0.5mm pitch VSSOP-8)? Is there a standards organization like JEDEC that "governs" these package names? Yes, look up IPC-7351B. Below is an excerpt from the standard. Image source

2017年7月21日 · I'm looking at two integrated circuit packages: SOIC and SOP. They seem (almost) identical (pitch, overall size, etc...) SOP SOIC Is there any important differences between these two packages th...

The SOIC is more than 50% longer than the TSSOP. (4.9mm vs. 3.0mm) and only a bit wider. That may not seem like a lot to you, but on a crowded board it might make a difference.

I am ordering some parts for the first PCB projects I've designed in EasyEDA. One of the PMICs I am utilizing is the TP4056 which is listed as being in a "SOP-8_EP_150mil" package. Doing a broader
