I'm not sure where in the world you are, but we supply a low cost, quick turn around BGA XRay service (with good operators who can interperate results). We are near Portsmouth in the south of england.

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'

Some key data is needed 1) how often does the HS 50 machines run? 24/7? 2)How many placements are being performed? I know for a fact Siemens Siplace S/F platforms require weekly preventative maintenance. Knowing the sophistication of the HS platform

I like what you're doing. 20 years ago anyone, hobbyists and tiny garage-shop companies could create electronics devices just as sophisticated and cool as big corporations. Today, SMT has largely trashed the creativity (and competition) that existe

Hi davef, couple of questions: clarifying costing of direct labor against overhead cost: an operator loading PCB onto the reflow oven is a direct cost, how about the reflow process time of the PCB while travelling inside the reflow, is that an ove

Not sure what software you have, but somehow you must be accumulating costs by process and you probably know [or can figure-out] how many boards you processed. From this, you can calculate a standard cost of a process. Continuing, there is a thread,

I have very little knowledge of pick and place machines or assembly, and was hoping someone could give me some advice of where to start looking. I do learn quickly so I am not afraid of challenges or learning through mistakes. I need to produce abou

Assuming you want to run 8 hours a day and 5 days a week, you need a sustained throughput of 2.5k components per hour. With fine pitch, futzing around, setup, etc you should really look for machines rated in the 4k to 5k per hour range. That's not sc

So let's see, Cost of Ownership = [[Equipment cost + Setup]+[Operating costs]] / [Yield*Throughput*Utilization], where 'Operating costs' include: chemicals, water, electricity, DI tanks, filters, recycling costs, etc.

All of your maintenance costs, grease, filters etc. on a scheduled basis.
