FAQs MORE
When does the turn-time begin?
Due to the complexity of determining the turn time of PCBA services, our policy is that turn-time begins immediately after all the parts and PCBs are ready and all the PCB files (Gerber files/other PCB files, etc.,), Centroid (Pick & Place PNP file, or XY Data or files in other formats), BOM, and all other necessary data or documents/images/photos are complete for our assembly work.[More +]
How do we quote the total price of PCBA service?
Our online instant quote system gives a rough idea of the PCBA cost, including the tooling, laser-cut steel stencil, and labor. In the case of Turn-key or partial Turn-key PCBA, the cost of parts will be added. We do not mark up the parts that we will source for you.[More +]
How do we handle the excessive and unused parts?
Excessive parts do exist because we will ask for some percentage of overage for consigned/kitted orders, or we will buy more for the same purpose for those Turn-key orders. You can either ask us to ship back to you these unused parts together with the loaded boards, or keep them in our shelf for your next order. All up to customers.[More +]
Do we assemble BGA? Any special requirement on this?
Yes. We can handle BGA of 0.25mm pitch with X-ray testing. For BGAs, we need to tent any vias under the BGAs with a solder mask to ensure the soldering quality.[More +]
Can we source some parts for your assembly?
Yes. This practice is called partial Turn-key. You can supply some parts, and we source the rest of the parts on your behalf. We will ask for your approval for anything that is not sure at our side. In case parts crossing or substitution is needed, we will again ask for your final approval.[More +]
What is centroid?
Centroid is the special file for assembly used for quickly programming the assembly machines. This file is also known as an insert file, Pick-N-Place, or XY Data. Some of the CAD tools will automatically generate this file and some not, but you may need to modify the file and then generate the Centroid file. The Centroid file describes the position and orientation of all the surface mount parts, which includes the reference designator, X and Y position, rotation, and side of the Board (Top or Bottom). Only surface mounting parts are listed in the Centroid.[More +]
