Yes, we are in the same boat. We get stuff unsealed, not labeled correctly, wrong packaging or all of the above. Im going to sit down with the purchaser here this week and get this figured out. Being packaged correctly still doesnt mean the parts arn

There is no standard as such. It's easy to see why. It's too complicated and has such a small payoff. Standoff is comprised of: * Package height * Solder thickness between the pad and the component lead * Delta of pad thickness and solder mask For p

Right folks, i'm sure we have a wealth of experience on here that needs to be tapped into! If you had to give on piece of advice to a fellow SMD operator/production engineer what would it be? I'll get it started, for me you must not over edit packa

We use Mydata PNP equipment, and are quite happy with it's speed and accuracy, especially with the latest version of the Mydata Tpsys software which includes a prototype version of their emergent auto-teach function for package sizes that can handle

Hello. I'm trying to find out if there are any standards with regards to how a PCB is packaged and shipped. I'm particulary looking for info in whether or not ESD bags are required for an assembly in a metal enclosure. Thanks.

you can reference JESD97 for labeling LF components, also. i have sent a similar letter to our suppliers and am fielding questions ranging from, what is a MBB to why such strict packaging requirements. i was surprised to know that the requirements

Hi Dave, Thanks for your response. HAST is an acronym for Highly Accelerated Stress Testing. Instead of the conventional PCT or Autoclave which requires say 168 hours, HAST can tremendously shorten the time. There has been correlation being estab

Hi Dreamsniper, the IPC land design standard is IMO a good reference. If you use the online calculator you can influence the result by varying for example manufactoring parameters. For the same lead width and same tolerances (and of course pitch) we

| Regardless of what various inspection standards state, has anyone got any information on how the strength of a soldered joint changes with the amount of solder in contact with the legs. ie if there is 0.152um depth of contact how does the joint st
