Printed circuit board inspection

Seamless PCB Manufacturing Checklist

When planning the fabrication of a printed circuit board (PCB), a lot of things have to be planned carefully in the right way.

If one step or consideration is overlooked, it may have disastrous consequences resulting in a malfunctioning board. Our seamless PCB manufacturing checklist will help you ensure every part of the circuit board is considered and potential mistakes practically eliminated.

Seamless Manufacturing Checklist

This checklist is how we process our PCB orders from start to finish for our customers.

Fill out the checklist below, download it, print it, and/or submit it to us to get started on a quote.

Be sure to go down the list and make sure all of these are checked to save yourself from all of the painful mistakes and headaches when you realize you’ve got something missing.

Checklist Item Criteria Yes No
1) MATERIAL: Do you have your material type (FR4 or other) determined?
Cu Weight Internal Layers: Do your Cu weight internal layers fall within 1/2 oz - 2 oz & line/space ≥.003 - Min. line/space ≥.006?
Cu Weight External Layers: Do your Cu weight external layers fall within 1/2 oz - 2 oz & line/space ≥.003 - Min. line/space ≥.006?
2) PLATING: Are holes and conductive surfaces plated per IPC-6012 Class II?
3) SOLDERMASK: Is solder mask required? For example: component side only, solder side only or both sides & color.
4) FINISH: Do you know which surface finish to use? For example: ENIG, HASL, Silver, ENEPIG, etc.
5) SILKSCREEN: Is silk screen required? For example: component side only, solder side only or both sides & color.
6) LOGOS & DATE CODE: Is the vendor UL logo & date code required?
7) TOLERANCES: Do you know what tolerances you will be using (finished hole tolerance ±3 mils, linear tolerance ±10 mils, or PCB thickness tolerance 10% ≥ 3 mils)?
8) FABRICATION & ACCEPTANCE GUIDELINES: Will you be requiring fabrication and acceptance guidelines that fall within IPC-6012 Class 2?
9) FILES: Are you able to supply manufacturing files? Example: drill/gerbers or ODB++.
10) FABRICATION SPECS: Do you have a fabrication drawing with specifications, tolerances, etc.?
11) FIDUCIALS: Do you have local fiducials for assembly?
12) ASSEMBLY: Do you have a BOM (bill of materials with part #s and notes), pick and place file (X & Y coordinates of the components), and an assembly drawing with reference designators, pin 1 locations, anode/cathode locations?
13) ASSEMBLY TYPE: Do you know what type of assembly this will be? (RoHS/leaded or clean/no clean)

Are you sure?
