We have a problem with soldering of a 96 pin header connector(9001-11961c00l1a from kingmate) we use 3 different wave soldering but in all of the machines we have many short circuit between the pins . the wave soldering machines that we use is fr

IPC-7711/7721 states under Scope section: "This document does not limit the maximum number of rework, modification or repair actions to a Printed Circuit Assembly". This is from Rev B of this standard. There are many factors that play a role in the d

Manufacturers of non hermetic SMT components have to test their devices as per IPC JEDEC 20C to check their reflow and moisture sensitivity. In this spec they pass them through reflow 3 times, then check them for damage and retest their performance.

Is there a limit to how many times a pcb with components can be run through a reflow oven before the components start to degrade? Example: We load the SMT components on the bottom side of the pcb and run it through the reflow oven. Next we load the

I'm not entirely sure that is accurate. The only people who want small 'desktop' machines are hobbyists/labs who are unable to accept the costs and time constraints placed upon them by a subcontractor and think they can do better themselves. Standalo

Hi, we do stepper motor assembly, and "use" both methodes; coil is selective soldered before entering line and then coils & I/O connector are soldered to PCB with robot (in many points also manual soldering) regards Dominik

You could talk to someone like Zebra labels about traceability using all the latest buzzword technology like IoT, RFID, NFC etc. Traceability will underpin many automated tasks, several elements of your SMT line can also dispense/read labels so you c

Hi Chics, It all depends on where you are in the world - in Europe robots were used back end (Ericsson), and usually Fujis front end (Motorola, Nokia, Ericsson). In China you're obviously not going to need the Robots.... Cheers, Rob.

Hi, So we are looking to automate a factory. We already have SMT assembly using robotic assembly line. Can anyone suggest or connect me to someone with technical expertise to implement this complete solution? We want to automate and also enhance th
