The large copper pours in the vacinity of this part make it essential that you get your thermal recipe correct. You may need to slow down your conveyor [decrease the ramp rates] in order to minimize the effect of the board has on the different heati

I am testing some BGA's (PBGA 30mm x 30mm) to evaluate the maximum ramp rate we can achieve in our reflow oven. Temperature is being measured at the body(top) of the component / not leads. After several trials (with various oven settings), the high

Hi, Why are you worried about ramp rate on the BGA? Do you have a delta T problem on your PCB? Regards, Grant

Could anyone advise what BGA rework rate we should expect with product that has 4 BGAs (224 pins, 196 pins, 160 pins, 48 pins). Negative factor is that we have old and tired pick & place - Panasonic MPA-G1 or MPA-V without AOI.

Hello. I am an HR Manager looking to benchmark pay rates for engineers in the Midwest with experience in reverse engineering and component level repair experience. The experience should be in BGA type repair with the core experience in setting the

Also look at the Chinese labour rate trend & the exponential growth in spending on luxuries (Cars, consumer goods etc.) At this rate we'll be their sweatshop in the next 10-15 years.

the copper forms intermetallics with tin to get Cu3Sn and Cu6Sn5. thus intermetallics formation consumes Cu and depends upon the cooling rate, faster the cooling rate, lesser the intermetallic formation

I'm new on this, what's the standard rate for each placement on passive and active components and how to rate labor cost per hour. thanks in advance

I was wondering what type of machine would be the best for high production rate of small pcb boards. A rate of somewhere near 800,000 units a month on a board that is approx 1"x2" 4layer with 20 components.

Is the flux rated for lead free? These higher temps will cause most lead rated fluxes to burn off prior to the wave. Jerry
