To predict whether or not a first pass part is going to come off during the second pass you need to calculate the ratio of weight/soldered surface area. According to a couple of different sources that I've dug up, maximum is around 44 grams/in.^2. I

Use a free cloud service like udrop or wetransfer. From your description, the plating is coming off the pogo pin itself ? Also, unless you absolutely cannot sub the part, consider the following vendor - have others as well that service the 'pogo p

Hi, We are currently working on a board that has 3x 50-pin THT at 1.27mm pitch each. This is too small for us to be able to consistently do on our selective solder. We are instead considering pin in paste. The connector we are using can be spec'd at

I was wondering IF anybody has has success wave soldering a 50 (2 rows of 25) pin 0.050" pitch thru-hole connector. I seem to be getting alot of bridging no matter what I do. Is there a design spec for the size and shape of pads? The pads on the pcb

Jason, where on the board is your connector?, front / back / middle? and where it on the PCB that you don't have issues with? Thief pad's are basically dummy pad's taht you have after the last set of pin's on the component are are used to draw the

Dear All, We are having a big debate over what is the industry standard in DPPM on the wave sodlering process. is a DPPM of about 800 satisfactory. As per our big bosses it should not be more than 50 DPPM. Is the figure realistic. We are typicall

| I need to know if there are any special component pad designs that need to be considered when evaluating paste-in-hole? We have a few through hole connectors that are good candidates to place pre reflow. Does anyone have sugguestions. | Thanks |

Currently, I am having problems with a AMP Mictor connector at the wave process. These connectors have both SMT leads(topside) and thru-hole leads. Even though we have re-designed the board for via issues. We still see some of the SMT leads re-fl
