Workmanship Standards

Mark Belec


Workmanship Standards | 10 April, 2000

I need some input to clear up some confusion I have with regards to what standard I should be using for workmanship on the pcb assemblies we produce. Should I be using the IPC 610b or the ANSI-J-STD-001B? What is the norm for the industry or is there one? What about the C versions of the above?

Mark: If you're looking for a baseline document for judging the acceptability of: * Mechanical assembly * Component installation * Soldering * Cleanliness * Marking * Coating * Laminate condition * Discrete wiring * Surface mounting of components

... of your boards, then you should be thinking A-610.

If you're aiming to manage and control your soldering processes, then you should be thinking J-001.

Either way, seriously consider version C. (That's the only version you can purchase from IPC, anyhow.) The following is a cut of the two document descriptions from the IPC web page.

Good luck Dave F

J-STD-001C - Requirements for Soldered Electrical and Electronics Assemblies With cancellation of MIL-STD-2000 and other Department of Defense soldering/material standards, J-STD-001C is the sole industry-consensus standard for soldering. This standard describes materials, methods and verification criteria for producing quality soldered interconnections and assemblies. This revision has easy to understand requirements for all three classes of construction. Full color illustrations are provided for clarity. Previous conflicts with other IPC and industry standards have been resolved. Co-produced with EIA.

IPC-A-610C- Acceptability of Electronic Assemblies A must for all quality assurance and assembly departments, IPC-A-610C illustrates industry-accepted workmanship criteria for electronics assemblies through full-color photographs and illustrations. The topics include component orientation and soldering criteria for through-hole, SMT and discrete wiring assemblies, mechanical assembly, cleaning, marking, coating, and laminate requirements.

IPC-A-610 is invaluable for all inspectors, operators and trainers. It provides the industry with a clear representation of electronics acceptability criteria based on the consensus of industry experts. Revision C has over 600 new and updated illustrations of acceptablity criteria and has been critically reviewed for clarity and accuracy. Expanded content over the previous revision includes more information on supported and unsupported holes, high voltage applications, jumper wires, and new SMT components.

The document's authors have contributed their expertise to making the document synchronize to the requirements expressed in other industry consensus documents, including IPC-J-STD-001.
