Three Special Reminders for PCBA

Parts Overages

Panelization

Break-away Rails (Break-away Tabs)

Reminders

01. Parts Overages

Proper SMT machine setup and operation requires parts overages. Unused and excessive parts supplied by you or purchased by us will be packaged and returned to you with the assembled boards.
SMT parts which are not supplied on the reels should be on one continuous strip of tape.
If you need to assemble the same SMT part in different boards, do not cut them into strips, please keep them in the continuous strip of tape or on the reels. Resistors, Capacitors, Diodes (0603, 0805, 1206, 2225, SOT, SOD, MELF - packages) require a minimum of 50 pieces and have to exceed the required quantity by 30 pieces. (E.g. 40 pieces will require 70 additional pieces –
this meets our minimum of 50 pieces plus 30 pieces over assemble quantity requirement).
Resistors, Capacitors, Diodes (0201, 0402, MiniMelf, miniature packages) require a minimum of 100 pieces having to exceed the required quantity by 50 pieces.(E.g. 80 pieces will require 130 additional pieces - this meets our minimum of 100 pieces plus 50 pieces over assemble quantity required).
A small number of excesses (1-5 pieces based on the total quantity of assemblies) are requested for expensive parts such as IC, BGA, QFP, Connectors, etc., this will ensure smooth assembling and shipping of your assembled boards on time.
For further information contact us at service@pcbgogo.com or seek help through our 24 hour online customer service.

02. Panelization

If your PCB dimensions are smaller than 50mmx100mm or if your PCB is of any shape
(other than rectangle) your boards must be panelized in an array for assembly.
As we also fabricate your PCB for you; once we start fabricating your board we will have the panelization file (solder paste data),
we will transfer the data to our PCBA department to create the stencil which will match the panelized PCB.

03. Break-away Rails (Break-away Tabs)

If the clearance between the board edges and copper features is less than 3.5mm (138mil),
or your boards need to be panelized for some reason,
break-away rails (Break-away tabs) must be added at the two longer parallel edges of the boards to ensure that the boards can be assembled by the machine.

PCB ASSEMBLY FAQ

Q: Who is PCBGOGO.com?

PCBGOGO is a PCB layout, PCB prototype, PCB mass production, and PCB assembly manufacturer in Shenzhen, China. We provide quick turn PCB fabrication and fast PCB assembly services to our clients.

Q : Do you accept to solder the boards that are not made by PCBGOGO.com?

Accepted.

Q: What files and documents do you request for my PCBA orders?

PCB file, BOM list, pick and place file (centroid file).

Q: What is centroid?

Centroid data file is a specific file containing all the required information used for placing the surface mount components onto the circuit board. This is also knows as insertion, pick & place, or XY data. Some of the CAD tools will automatically generate this file and some may not, but you may need to modify this 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 board (top or bottom). Only surface mounting parts are listed in the centroid.

Q: How do you request for the shipping and marking of the parts for the consigned or kitted order?

We hope you can mark on any individual package or box with the corresponding line number on BOM, manufacturers’ part# or customers’ part#, quantities. A detailed packing list is preferred to enable us to count and check upon receipt of your parts..

Q: Do you offer turnkey PCB assembly service?

Surely 100%!

Q: Do you assemble BGA? Are there any special requirements for this?

Yes, we have the ability to handle BGA of 0.25mm pitch with X-ray testing. For BGA, we need to tent any vias under the BGA with solder mask to ensure the soldering quality.

Q: How do you quote the total price of PCBA service?

Online quote is only for PCB assembly fee. If you need turnkey PCBA service, we will quote your PCB cost, PCB assembly fee, and components with shipping freight as total amount.

Q: When does the turn-time begin?

Determining the turn-time of PCB services before the parts are collected is quite complex and is not accurate. Therefore 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, XY data or files in other formats), BOM, and all other necessary data or documents/images/photos are complete for our assembly work.

Q: 10. Is your assembly RoHS compliant?

Yes, but we also offer leaded PCBA services.

Q: What are your PCB assembly standards?

IPC-A-610 Class 2.
