I'm constantly being flooded with information by sales reps on x-ray and other types of equipment to inspect BGAs. Most of these items are simply beyond our capital budget constraints. I've witnessed dozens of demos, and to be honest, I really don'

Here's what I know about SMEMA and SMPI: SMEMA: An organization within IPC focusing on defining physical and computer protocol interface between production machines. Most equipment suppliers design their machines to physically meet SMEMA requireme

The machines you choose depends on the boards you build and how many of them you build. Assembleon is designed for faster production speeds where Juki is more flexible. Why are you just looking at these two? Aren't they in different leagues? Why not

Hi Does anyone know of any studies carried out comparing long term reliability of BGAs with their equivalent QFPs etc. If you were designing a critical product in the aerospace field would you go for the BGA or QFP version of the same IC? Based on

The root cause of your problem is your placement equipment. It is not designed for continuous production during component replenishment. Feeders that can be removed, reloaded, and placed back on the machine while the machine is running (without mis

We are developing a new product, and some of the designers are proposing QFN packages. These look like leadless QFP's. We don't currently use anything like this, but we operate in a high reliability automotive market. Can anyone provide advice/com

Thanks for the advice. In this scenario we are designing our own product. Currently we are building at a prototype level with no appreciable wait between reflow passes. The part in question is a 64 pin QFP. We use a BTU VIP 98 with edge conveyor.

I cannot give references to papers, etc, but I can tell you from experience that High Impedance circuits and High Power RF circuits are not something to try no-clean on. For an aerospace customer, I had a circuit that any residue left between two pa

No chart for you, but I will comment that a prudent product manager would require a substantial reason to accept the risk of product failure and loss of profit to redesign his / her product. We merrily assemble many boards each month that were desig
