Has anyone changed the PD on this part lately. Sounds like a program (PD) issue. Nozzle size should be .7mm. Narrow view should be selected. Tape leaf cover on feeder should be .7mm. Make sure parts aren't on the camera lens. Good luck!

You are welcome and thank you for all the inputs. You are right in that these new machines have the camera vision. Like I said in my other post, my engg's like all the machines but prefer Universal and Mydata for a bit more available flexibility like

Another variable is whether the ground pads have proper thermal reliefs. If the pad has solid ground plane around the perimeter, the heat being applied will quickly dissipate to the surrounding metal. A proper relief of the pad will prevent the hea

How can one go about defining the complexity of a PCB for characterizing reflow profiles A large balanced board may be easier to profile than smaller unbalanced board ? Any ideas how to define an index to calculate the complexity based on size,weig

I agree the Ersa Power tool is probably the most powerful iron on the market, unless you want an iron that takes two hands to hold. We have put the power tool against many irons and none have the capability or power, it should work well for you, and

Anyone have any experience with immersion white tin over copper plating? We are seeing opens develop under BGAs after we bake and conformal coat. And when we lift the parts the pads are 60% of the original size. Need some advice on possible causes

We have a 1.6 mm thick automotive PCB board of size 35x70mm. One of our vendor has given us a batch with lesser soldermask thickness 5~8 microns. Will this affect the circuit board on a long term. What should be standard for the soldermask thickness?

PCB is 12.25" x 4". There are large MOSFETS on the board. Two large Electrolytic Caps. Two Large Multi-Layer Ceramic Caps. 15 C Size Tantalym Caps. A fair number of IC's, (SO-8's, SO-16's). No BGA's or finepitch of any kind. The board is double sided

I would contact your PCB supplier, they usually have some type of software for panel optimization. Each shop potentially uses different size panels so it is a good idea to ask them what they are using and go from there. Keep in mind that there are

Hi, Our local suppliers keep running out of passives, and it's becoming annoying. Does anyone know of any large component suppliers who sell passives, and often keep stock? We would like to find large US or overseas passive component suppliers for
