Help, I have a customer asking if our shop conforms to IPC-a-610 class 2 specs. He is asking if our Humidity is kept under 40% and if we have a particle count under 5MG......where can I find info in the IPC spec on humidty and particle count in the

The problem you create by soldering from solder destination side (presuming you have already soldered from other side) is that you will trap air in PTH so you have virtually no continuous solder in PTH from one side to other. This will not meet IPC-A

We expect aerospace to be IPC-A-610, Class 3 and J-STD-001, Class 3. The above quality statement stecifies: * "IPC 610, Class 2 acceptability." This is unclear. Should this be "IPC-A-610, Class 2 acceptability?" * No class for J-STD-001. Should we a

Hello, Looking for a solution to silicon conformal coating wicking up into connectors. We build IPC-A-610 class 2. We are using a PVA 650 with Dow Corning 1-2577 conformal coating. We have solder joints that must be coated 1.25mm from the connecto

I am looking for an industry standard �stock� note to place on our printed circuit board assembly drawings that will capture a level of cleanliness for an IPC-A-610 class 2 board assembly. I�m looking for some quantitative spec for cleanliness that w

IPC-A-610 uses words to the effect that it�s a Class 2 process indicator, if either: * Entrapped or encapsulated solder balls that are within 0.13 mm [0.00512 in] of lands or connectors, OR * Entrapped or encapsulated solder balls exceed 0.13mm [0.00

Steve, We are touching up 6 - 12% of all solder joints processed. We consider the solder joint to be the focal point of the SMT process. Therefore our metric is based on it. For example in a given month we... 1. Assembled 25pcs of 'A' (IPC-A-610/J

Q1: Are the markings on resistors the actual value? A1: Generally, resistor marking indicates the value of the device, where the first two digits are the value and the third digit is the multiplier. Q2: Do AOI machines look for these markings or do

I've been tasked with finding out how difficult it would be to convert our company from a Class 2 to a Class 3 supplier. Does anybody know if there is a "how to" manual available to assist me in getting this done. Short of going thru all of IPC-A-610

Can someone helps to interpret the IPC-A-610's requirement on solder balls ( less than 5 mils in diameters.). We found about 6 to 10 balls ( less than 5 mils ) scattered in a 600 sq mm board. Is it consider failing for class 2 product ?. Thank you.
