FAQ
What kind of capacity do you handle?
We do not limit the quantity you wanna quote. our capacity for SMT is 500 thousand pick-and-place soldering point per day, 100 thousand DIP soldering point per day.
What other services can you do besides PCB fabrication and Assembly?
STG has a capability for PCB layout design as well as re-engineering according to customer's requirement. For mechanical assembly, we would require a sample or specific assembly instructions. For special requirement such as burn-in test and conformal coating, your test procedure is required.
Please submit an RFQ or give us a call to discuss you needs.
Do you handle PCB fabrication and re-engineering?
for instance,we convert DIP type into SMD type by re-engineering the design without sacrificing the function.we have a design team for PCB layout. charge depends on the layer number, complicatedness, function, etc.
Do my boards need to have silkscreen for assembly?
It is not required, but it is preferred. If you are submitting boards without silkscreen, we will need to have some other form of documentation to verify component placement and rotation. Orders with boards that have no silkscreen need to be reviewed.
What kind of surface finishing could you handle?
We can handle OSP,HASL,Gold immersion, silver immersion with RoHS and Non RoHs.for technical datasheet, please refer to our website:www.China-pcbassembly.com.
What kinds of base material do you use for PCB fabrication?
We generally use normal FR-4,(epoxy or fibre glass), we can also provide high TG FR-4 that meeting stringent requirement on temperature.
In addition, we can handle FR-1,FR-2(94V0), CEM-1, Aluminium base material according to customer??s special requirement.
The specification has 0.8mm,1.0mm, 1.2mm,1.6mm, 1.8mm, 2.0mm,2.4mm thickness.
What does the quote include?
The quote includes PCB fabricating, E-test or probe test,solder stencil, components cost, placing components on the boards. The SMD component placed by machine will be reflowed, while the thru-hole components by hand will be wavesoldered. Function test, and selectable anti-static packaging.
Welcome to your inquiry , no matter by call or by e-mail, we will try our best to selve your question and problems!
