Hello Bill, Ioan's idea's are good. One more thing that you may want to consider is using a "Home Plate" aperture on your stencil for the aforementioned caps. The idea is to put a smaller amount of solder paste directly underneath the component. This

Our R&D people are looking at the possibility of "Silver Through Hole" as an alternative to "Plated Through Hole" for our future PCB specification. Do any of you have any experience of this, advantages/disadvantages, etc. I'm told that the main reaso

We are going to hand place through hole connectors by screening them top side in a double sided reflow board. I saw this done before sucessfully on a daily basis but is there anyone with a paper or specs as to what aperture size, any special pad cons

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

I'm needing some info in regards to the usage of a Wave Rider. What is it basically used for? I have to implement one into our process and I'm trying to find out what some others use it for. This is going to take the place of our Slim Kic and glass p

1. Spec references for max allowable untinned gold near glass seal and case body? 2. Low cost mechanical dip system to facilitate tinning of DIP parts. (Low volume; currently using hand solder iron techniques to allow for max coverage without bridg

Assuming agressive design rules what is the minimum distance I can get away with between the board edge and a SMT pad and between the board edge and a plated mounting hole ??? (The board is only 1"x2" and the mounting holes are 80 mil dia, 125 mil

I' ll have to agree with Dave on this one. Just get the information from the Suppliers. The Glass plate, Aluminum board, Glass slugs, etc... are all used to determine if a calibration is needed or if it was succesful.( they can also give you offset i

You're correct that some folk have used microns and other folks have used u" when discribing their ENIG specification. It's likely the the micron folks misquoted their units and it's arguable that participants in the forum should have taken them to

u" are smaller. 1uM = 39.4u" and so 3-7uM = 118-275u" Then some articles or specs really confuse things by mixing mm and uM or using u all by itself... http://www.circuitree.com/CDA/ArticleInformation/features/BNP__Features__Item/0,2133,11666,00.h
