Prototype PCB Assembly Services

Let BEST be your assembly source for prototype PCBs. The same quality of work that we have been performing in reworking your critical PCBs quickly can be expected for your critical first product builds. Whether you supply the parts or we do, our certified soldering technicians can turn out a quality product. We can handle the prototype (5-30 pieces) through medium run (200-300 pieces) assembly projects.

Save time and money by providing your own parts drop shipped directly to our factory. We only start work after all the parts are accumulated and ready for assembly. BEST will help you overcome your production capacity constraints.

Real-Time Manufacturing means delivering electronic products when they're needed, especially prototypes. Rapid prototype work demands instant response-we are dedicated to insuring a fast turnaround just like you have come to expect in our rework/repair services.

BEST offers premium service when your project is down to the wire on a trade show or critical demonstration. We've been there and we know how to perform!

If your market is requiring lead-free solder for circuit card assemblies and you need several evaluation samples built from lead free solder then BEST is your answer

BEST is prototype and micro OEM printed circuit board assemblies built for speed!
If you are a micro OEM or a start-up business and need to build small quantity PCB assemblies or fully functional enclosures on a routine basis and are not getting the attention you deserve then BEST is your answer

If you need to build your first engineering prototypes because you have respun the design, or are just need to get the first revision of the design completed so that you can debug and test without questioning the workmanship then BEST is your answer

If you need a highly motivated business that you can rely on to get to that working prototype to field testing, to that important trade show or to that investor group for the presentation BEST is your answer

Our experience includes:

• Manufacturing expertise from a range of small, medium and large contract manufacturers
• Rework/Repair experience with one of the preeminent rework and repair facilities
• Training and soldering workmanship expertise including IPC master and 2M instructor certification

What BEST needs to build your fast turn PCBs

• The clock starts when funds have been transferred to BEST, we have your shipping info and the last parts have been received. Parts received after 12:00 pm CST are considered received the following day. BEST is conveniently located in the middle of the US near a major international airport (Chicago) for fast shipment anywhere in the world.
• We require all build data 24 hours prior the receipt of parts. This data includes:
  1. Bill of materials in Excel or Delimited Format
  2. Customer drawings including any special instructions
  3. Gerber files provided on CD or uploaded to BEST FTP site
• 5 or 5% extra parts (whichever is more) for all SMT passive components, 20% for 0603 and smaller devices
• For larger active components (including BGAs) we ask for 1 extra, to compensate for any damages.
• We expect that the PCB has reference designators & polarity signs be clearly marked.
• All parts with pin 1 or polarity must show some visible mark for identification. If a part is not clearly marked with polarity indicators, customer will have to provide that information.

• We log in and inspect all kitted parts prior to the beginning of the prototype build, checking it against the supplied documentation.
• If we are provided the incorrect part (according to the BOM) we will not place it and notify you in our production report when the boards arrive.
• In the event of a shortage, we will contact you by phone and/or e-mail and postpone the build for as long as 1 hour, in order to resolve the problem.
• If you would like us to stop the PCB build and resume once parts have arrived, we will charge an additional 20% of your order amount to stop and then re-start the assembly process.

• We are shipping to an address in the US
• All kitted parts match their respective pads on the PCB.
• All kitted parts, including the PCB, are defect-free
• All necessary data is received 24 hrs prior to the arrival of the parts kit.
• The Gerber file and BOM both have reference designators.

  All orders received after 12 p.m. CST are considered received the following day.

• BEST warrants each assembly for workmanship up to 90 days after shipment. BEST will repair the assembly or credit the quoted cost of the placement at our option.
