Customer Reviews
They have already used our products and services.
“We used to assembly our boards locally since we are afraid of fake components in China, but your PCB and assembly quality of our testing main are excellent. Thanks to your services and FAB skills. I will contact you in the next month or so for three different boards that I am currently working on.”
"We have been Viasion's customer for more than 10 years. Sometimes we have been contacted by new PCB company with cheaper price, but your good service and quality is too good to allow us to change. There are very very few problems from you during these years, and if needed I can get a quick reply andsatisfied solution if something does happen.”
“I am really impressed by your attractive price and short lead time. And I think the quality is good as well since we did not get any compliant from our customers. I am very satisfied with your service, and have decided to place more orders in the following weeks.”
"Viasion has a great team in engineering, production and customer service. They have supplied us with PCBs since 2007, always good quality, on-time delivery and quick responsive. Besides, they are very good at one-stop PCB fabrication and assembly service, including purchasing all electronic components. "
"It was our first order with Viasion and our first time outsourcing PCB fabrication and assembly, and we were hoping things would go smoothly. I can say that things went better than we could have hoped. The quality of the PCBs looks very good. The boards arrived packaged well, and having the assembly done saved us a ton of time. "
"We were a little worried about the quality since it was our first time ordering printed circuits from Viasion. But we received high-quality boards in two weeks. The best part is that the service we received was all done with a big cost savings over what we were paying previously, and Viasion was helpful and attentive to our needs."
