Frequently Asked Questions

Yes.  Winow New Energy has no minimum order quantity requirements and can assemble even one board.  For more information please check our Prototype Assembly page.

Parts individually packaged and labeled with BOM line item number and either Customer part number or Manufacturer's part number. An inventory list of components in the kit indicating Manufacturer's part number and Quantity in kit. If SMT parts are not on reel, parts preferably should be on continuous tape with a leader of no less than 6" to account for machine attrition and potential scrap.

Yes we can do partial PCB assembly for both kitted/consigned orders or for turnkey.

Component footprint should be made per manufacture recommendations for pad size and mask clearance.  All BGA type devices are required to have all vias under component tented with soldermask.

We return all unused parts to the customer whether kitted/consigned or turnkey.

We will provide you pricing for PCB assembly. The PCB assembly pricing includes tooling, solder stencil and assembly labor for loading the components.  Our turn-key quotes also show component pricing as indicated.  We do not charge setup fees or NRE's for assembly.

Assembly turn-time begins immediately after the PCB turn-time and when all parts and information received complete.  If consigned kits and documentation is incomplete, assembly turn-time begins when all necessary assembly information is complete and on hand.  Any delays due to CAM Hold and/or technical issues will impact turn-times.

Yes.

PCB’s are required to have a format with breakaway rails of 0.5” on at least 2 opposing sides. If rails are not present we can build individual boards provided the following criteria is met: 1-up PCB size is 2”x2” (51mmx51mm) or greater, each 1-up PCB must have fiducials, fiducials must be a minimum of 0.118” (3.0 mm) from the edge of the PCB, no component can be closer than 0.196” (5.0mm) from the edge of the PCB.

If after receiving your loaded boards you run into problems of any kind, contact us at once.  We will evaluate the issue and repair/rework or remake as may be appropriate after determining the root cause of the problem.  For any returns, we will issue you a RMA number.

Normally the testing plan is recommended for the turn-key service( from PCB fabricating, part sourcing to PCB assembly). As we mentioned above it is a complex work that possibly encounters errors/faults, the functional testing as the last checkpoint for the quality control, it can detect the most of defects and ensure the quality of PCBA before shipping out the assembled boards.
