We find that baking PCB assemblies at 90 degrees C in a Blue M forced air oven is safe for most all PCB's that we have encountered over the past 12 years. We remove any external plactic hardware that may be attached to the assembly and also like to

Hello, I am writing a software that deals with chip placement on PCB and I would like to know if there is some standart way to describe what are the coordinates of the chips on the pcb, I know that Gerber file contains all the drill holes and tracks,

The format is X,Y Theta of the component center for all placement machines. Gerber data can be useless, unless you have the reference from pin 1 to the component center. Some machines offer a CAD convertion tool. I don't know any machine, which can

I'm using a CIM software (http://www.aiscorp.com/products_npi_circuitcam.htm) to import gerber files and produce pick&place programs and paper/paperless documentation. It's very friendly, useful and fast, but not cheap. I don't know any other softwa

I agree with Nick. You should check with the manufacturer to determine what type of plating is used on the components and see if the manufacturer has any recomendations on materials that may help. If no exotic materials are used, the culprit is most

Hi! From your post, it seem like the wave did not really touch the component. You probably need to get the both wave height correct and that it hits the component.It is normal for solder to come through the PCB when using chip wave. The through-hole

Check that you are getting an even spray pattern from the fluxer.Check that the chip wave nozzle is clean and if possible feed the PCB in to the wavesolder unit at 90 � or 180�.

Hello !! I have a problem with my wave solder oven, in one of the products we made has connectors on one side of the pcb and in the other one has SMT components the process is kinda tricky on the SMT components we use an adhesive and put to the refl

Hi We are experiencing serious problem with ceramic capacitors. They are with low electrical resistence and the problem is intermittent. We found some of them with micro cracks but not all. What could be the causes for this problem? We are su

Having just gine through a similar problem myself (with much less equip.) Here are a few things to consider and/or look at Do you have the proper pad size? It should be the same size as the pad on the BGA. Is the board warping during your operati
