Are you sure? Class 3 is for extremely high-stress / high-reliability situations. More info...
Add PCB Fabrication
Screaming Circuits and Sunstone have partnered to let you quote & order fabrication along with your assembly job. Check the box at left, get a quote on the following page, pick your turnaround time and submit. Sunstone will fab your boards and send them to us for assembly. Easy! Learn More…
Save time by having us provide your parts! We'll use your Bill of Materials file to give you an instant quote.
Desired Board Quantity
The number of PCBs you would like us to assemble.
Total Unique Parts (Number of BOM line items)
This is the number of different part numbers used on your PCB assembly. In
other words, if you send us a box with all of the parts, how many different
bags will there be? In most cases, this is the number of line items in your
Bill of Materials (BOM).
For example, a 10k resistor and a 1k resistor would be considered 2
Manufacturer part #s and a 20k resistor used at 4 different locations, R6, R7,
R11 and R15, would be considered as one Manufacturer part #.
Double Sided SMT?
Are there surface mount components on both sides of your PCB?
Do you need lead-free RoHS (Reduction of Hazardous Substances) processing? If
so, we will build your assembly with fully RoHS compliant process and supplies.
The total number of surface mount parts to be placed on the board (Example:
0805 resistor or TSOP chip). This count should not include any parts listed
below in the thru-hole or BGA/QFN/Leadless boxes.
The total number of thru-hole parts. (Example: Axial leaded resistor). Note
that thru-hole connectors count as one each, regardless of the number of pins
The total number of surface mount devices that have a spacing of 20 mils (0.5mm) or
less from lead center to lead center. (Example: QFP with 15 mil lead pitch)
A BGA (Ball Grid Array device), QFN (Quad Flat-pack no leads) or other parts
without leads. These are surface mount devices with all interconnects or solder
joints under the device. Screaming Circuits does 100% post assembly X-ray
inspection of all leadless solder joints.
Class III describes the inspection
level that is performed on your assembled PCBs. IPC 610 states that Class 2 is
standard commercial level inspection and Class 3 is an enhanced level intended
for high reliability applications. Screaming Circuits inspects to Class 2 by
default and will inspect to Class 3 upon request and for an additional fee.
NOTE: Class III inspection is only available for Full Proto and Short Run
Projects protected under the United States International Traffic in Arms Regulations (ITAR) require special security handling. The ITAR classification is typical for projects produced for the US Military and other national security interests. Screaming Circuits will provide full ITAR compliance when the ITAR option is selected during the quote process. Screaming Circuits is not licensed as an exporter or registered as a broker under ITAR.
