There is no current standard for the amount of flux that should be applied to a board. Current standards focus on what the result of a process should be, not how the process should be performed. So, the standard tells you that you need a procedure de

Adding to my previous message this could be solved fairly easily for the general case with a jig made from 3.2 - 4mm aluminium aircraft grade plate. you would machine the bottom side edges to give a 1.6 mm thickness, then machine the top side to leav

Thanks for your reply, Rob. I wish I could attach images here, but despite the option for 'attachments,' it won't let me attach. The pendulum mechanisms are the cheap plastic type, from China, not the older style mechanical ones. Not sure if this l

I'm no clock expert, but, even that unit you linked appears to have the period set by the weight on the pendulum. That unit notes that the pendulum is adjustable....though, I'm not sure how/what is adjustable...I would expect it to be the weight. I

We are planning on using a chip that is available in LGA or Sn/Pb balled BGA. The package dimensions are the same. Pitch = 1.27mm. We are using a Sn/Pb soldering process and no clean paste (wash afterward) for high reliability Class 3 assemblies. Fai

I've dealt with MyData, Assembleon, Fuji, and Juki over the last 9 years with the majority being MyData and Juki so I'll talk about them. MyData was very nice for high mix/low volume due to the ease of setup and smart feeders, but I felt like I was

Hi, we are looking for 1 or 2 new postreflow AOI machines to replace our old ones and possibly 1 prereflow AOI(we never had pre reflow before). In our company we run low volumes and high volumes. I have been looking at Viscom, Mirtec mostly, Cyberop
