Two experiences of completely different quality. First one made me feel like they really respected me as a customer. Second one, their customer service was abysmal and they resorted to practical extortion in the end. Perhaps they had a change in upper management between these two experiences.Edit: The delays caused by the footprint errors on my side do not reflect my review here. Also my review does not touch on the delays at all...The extortion I refer to is the retroactive charge for services that other companies provide for free typically through online programs (such as Bay Area Circuit’s instant DFM). In my previous experiences with board houses, I did not face a charge due to DFM’ing. When I brought this to the attention of a Gorilla employee, I was informed that these new charges were related to a management change. I call this practical extortion because I was only informed of these charges deep into this process and I would incur further delay if I choose to not pay these charges.More frustrating, most of the board DFM issues that you picked up were related to via sizes. I found the specifications about your via capabilities to be unclear. In your capabilities, you list your minimum FHS as 4 mils, a minimum annular ring as 1 mil and a minimum pad as 8 mils. I confirmed this via sizing with your team and designed vias of 4/8. However this was incorrect and I had to resize my vias to 4/16 to meet your DFM requirements. I’ve attached a snip of your fab capabilities to show the source my confusion.The customer service being abysmal relates to the combination of the previous surprise charge and your internal communication issues that added unnecessary delays due to unnecessary re-quotes. Internal communication issues which meant that If I hadn’t pushed back at particular point in this process, the wrong board would have been fabricated.During this whole process, I tried very hard to be polite, respectful and prompt. I find it disheartening that in your reply to my review, you choose to emphasize a mistake in our board unrelated to my comment in general. This is exactly why I described my customer experience as being radically different between my two runs.

Ive used Gorilla Circuits for several quick-turn prototype projects now. The quality and pricing has been great. My circuit board assemblies have come back quickly and without problems, even when complex HDI structures and fine pitch BGAs are present in the design. The sales team is responsive and quick to get back with a quote. Gorilla has also been great about full turnkey services such as purchasing parts, sorting through BOMs, and helping resolve issues so I can get back to my other tasks quickly. Highly recommended.
