We are more than a prototype shop. MacroFab offers full turnkey services that take you from prototyping PCBs to drop shipping fully complete products to your customer’s door. Engineers can use our self-service platform to get quickly started with prototyping. When you are ready to scale your product, our project managers and network of partners are here to make it happen. Our team will help you scale through high volume production while our industry leading customer service team makes sure your experiance is as smooth as possible.
Prototype services, high mix low volume runs, and first articles of products are built and assembled in-house at our facility in Houston, Texas, USA.
Our assembly line includes Mycronic MY200 and MY300 pick and place machines, Mycronic MY500 and MY700 paste jetters, Heller 9-zone reflow ovens, and RPS Rhythm Selective Solder machines. We also have process ovens for MSL requirements, automated wire cutting machines, and a wide array of hand-soldering/rework systems on our line.
High volume orders may be processed through our manufacturing partners running MacroFab processes and software. All manufacturing partners are certified and vetted by MacroFab.
More information about what kind of assembly classes we offer can be found on the Quick Turn, Prototype, or Production Class Service article.
The typical assembly process for an order at MacroFab is the following.
We support through hole, SMD, both leaded and leadless, BGA, LGA, PTH, hybrid, SoP, and daughter-board style components. We do not currently support chip-on-board components. Inquire about support for stacked packages and flip-chip, which can be done on a case-by-case basis.
The parts to be assembled onto a PCB must be equal to or larger then the following specifications.
|Chip Components||Resistors/Capacitors||01005 10 mil x 05 mil (0.25mm x 0.0125mm)|
|Leaded Packages||SOIC/QFP/TSOP||11.8 mil (0.3mm) Lead Pitch|
|Leadless Packages||QFN, TQFN||11.8 mil (0.3mm) Lead Pitch|
|BGA||BGA/FBGA/LGA||15.7 mil (0.4mm) Ball Pitch|
For information about PCB manufacturing limits and Design Rule Checks (DRC) check out the knowledge base article PCB Specifications and DRC.
We support double-sided assembly at no extra charge.
Unless otherwise requested, all assemblies are built to meet IPC-610-D Class 2 acceptance criteria.
We follow all ESD safety procedures as documented in IPC-A-610. All of our work benches are grounded, and our floor is coated with a conductive sealant. Operators wear wrist straps at work stations, and heel straps for moving around the facility and moving product. All circuit boards are packaged in ESD bags prior to shipping.
All assembly processes at MacroFab are designed to be RoHS compatible. We use SAC305 solder paste for surface mount components and SN100 solder for touch-up and through-hole soldering.
We are unable to use leaded, non-RoHS, or HMP solder in our processes.
We currently use water-soluble fluxes and no-clean fluxes in our assemblies. All boards are water-washed during the assembly process, but small amounts of no-clean flux will remain after washing.
If you have a board component that is water-sensitive, please see the knowledge base article on The Parts Placement Screen about adding a note to the part for our Manufacturing Technicians.
All PCBs are 100% E-tested at the board house to ensure electrical verification. We can implement all customer established PCB assembly programming and testing procedures. All that’s required is a list of your needed equipment and documentation of your instructions. If you don’t yet have a procedure or need assistance in creating one, MacroFab can help put you in touch with the right resources through one of our many 3rd party vendor relationships. Let our sales team know of your specific requirements!
We can implement conformal coating on orders of any quantities. Our typical procedures involve masking and then coating the PCBs with a specified conformal coating. If you require conformal coating for your PCB assemblies, please contact our sales team to get a proper quote.
