FAQ

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.


Can Customers consign the components or bare pcbs?

Yes,we accept consigned components,you could provide any components that hard to source and cheaper than we quoted.


Can we provide also box build and final assembly?

Yes,we could.


What is your delivery policy?

Standard lead time for turnkey pcba samples is 2-3weeks

Standard lead time for turnkey pcba mass production(above 100pcs) is 4weeks

We will inform in advance if the lead time is longer than standard lead time(maybe because of holidays or special materials or peak season)

We guarantee that we will ship at least 100% of your finished PCBA within the promised lead time,unless there is holiday or power failure.
The assembly order does not start until the last component is received, so occasionally there are delays in receiving material that are beyond our control and therefore not considered as a late shipment.


On turn-key orders, what  do about part crossing or substitutions?
GreenTeck holds no inventory, therefore we will not substitute parts on your bill of material with parts we already have. We can suggest crosses or assist with component selection if necessary, but we require customer approval before ordering.
 
How to order components for Turn-Key orders?
We order to your exact bill of material ordering 3-5% extrafor most components. Occasionally we are faced with minimum / multiple orders where extra components must be purchased. These parts are for approval received from customers prior to ordering.
 
What is the lead time on a turn-key order?
Components procurement lead time is in addition to assembly lead times mentioned in our quotation. 
We can start the PCB production while we prepare the material, so we can shorten the whole lead time as much as possible. 
For Prototype, it is usually within 2 weeks based on single or double PCB. And another week  for multilayers boards. For mass production, it is about 20 working days, less than 1 month for large volume.
 
What do I need to send for a turn-key order?
Bill of material, complete with information in excel format.
Complete info includes  manufacturer"s name, part number, ref designators, component description, quantity. 
Complete gerber files, we accept PCB file, Protel file, PCAD file as well. 
For conformal coating ,special test requirement or packaging, please specify before quote.

What are the payment terms? 

100% T/T in advance for small volume, T/T  50% in advance for large volume if needed.  An up front payment equaling the cost of order or 50% of order is charged with the balance being charged upon shipment of the order. We are flexible and could have a discussion about this.  


Which gerber layers do you need for assemble?

At a minimum we need silkscreen, copper (trace layer) and solder paste layers for assembly. We prefer you to send us all gerber files generated by your CAD program.


Can you handle lead-free builds?
Yes, we can handle Lead-Free PCB fabrication and Assembly.
 
What standards and certifications does GreenTeck  follow?
GreenTeck is certified ISO9001:2000 
We inspect to IPC-A-610, Class II 
We adhere to RoHS Directive 2002/95/EC
 
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?  
GreenTeck 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 your 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.

 
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 has0.4mm,0.6mm, 0.8mm,1.0mm, 1.2mm,1.6mm, 1.8mm, 2.0mm,2.4mm thickness.
