Frequently asked questions

Electronics Finder' parent company, GID Industrial, specializes in procuring industrial parts. We know where to find the rare and obsolete equipment that our customers need in order to get back to business. We stand apart from our competition through our commitment to quality, and look forward to the opportunity to show you how.

The warranty we offer will be based on what we negotiate with our suppliers. Sometimes, a part will be sold as-is and without a warranty. We usually offer a one-year warranty for single board computers in particular because they are our specialty.

We use FedEx, UPS, DHL, and USPS. We have accounts with each of them and generally ship using one of those, but we can also ship using your account if you would prefer. We are able to ship with other carriers if you would find it more convenient.

Electronics Finder will definitely serve you. We work with international clients all the time, which means we are regularly shipping goods all across the globe.

Visa, MasterCard, Discover, and American Express are all accepted by Electronics Finder. We will also accept payment made with wire transfer or PayPal. Checks will only be accepted from customers in the USA. Terms may be offered (upon approval) for larger orders.

HARD TO FIND A BETTER PROVIDER

Our company provides services to aid in the manufacture of technological products, such as semiconductors and flat panel displays, and often searching for distributors of obsolete product we require can waste time and money. Finding GID Industrial proved to be a great asset to our company, with cost effective solutions and superior knowledge on all of their materials, it’d be hard to find a better provider of obsolete or hard to find products.

Applied Materials

CONSISTENTLY DELIVERS QUALITY SOLUTIONS

Over the years, the equipment used in our company becomes discontinued, but they’re still of great use to us and our customers. Once these products are no longer available through the manufacturer, finding a reliable, quick supplier is a necessity, and luckily for us, GID Industrial has provided the most trustworthy, quality solutions to our obsolete component needs.

TERRIFIC RESOURCE

This company has been a terrific help to us (I work for Trican Well Service) in sourcing the Micron Ram Memory we needed for our Siemens computers. Great service! And great pricing! I know when the product is shipping and when it will arrive, all the way through the ordering process.

Trican Well Service

GO TO SOURCE

When I can't find an obsolete part, I first call GID and they'll come up with my parts every time. Great customer service and follow up as well. Scott emails me from time to time to touch base and see if we're having trouble finding something.....which is often with our 25 yr old equipment.
