Listen.I posted this same message on a diffrent thread but got no repsonse. Here's what im wondering Im more of a wave guy but we had a good employee in the engineering department, he's left the company but he used these setpoints on the ovens in a

yes! i though this thread looked familiar! looks like it has been repeated....even the response from muse is very very familiar...that, or i am have a serious attack of deja vu! thanks for the requote though.......by doing some research I decided to

I solder a lot of differnt products throught a Reflow oven that are non PCB baised Axial leaded components typicaly, mounted vertically in jigs. where i can for cost reasons I use aluminium jigs but you have to experiment with the thermal mass and de

Hello All, Could someone offer suggestions to cure poor BGA reflow that is limited to the same area of the BGA and on one type of board only. The reflow has the look of "baseball caps" and is positioned such that it is the leading edge only that doe

No problem . . . I have been throught this road before. Here is another heads up, if you ask for "thermal profile data" you can get the following: 1. a graph showing several thermocouples reading air rather than board temperature. 2. graph where e

we have a small batch oven. It is does take a long time to cool but we set up an airline that blows in the door when its open and that helped things a lot. looking at the hot plate your thinking about going with, it doesent look like you can program

An option to consider is leave top and bottom heaters settings the same; to get correct liquidus time and temperature on one side, you will have some amount of reflow on the second side. If you have BGA's, QFP's on the bottom side yet they are smalle

Hi We have a new product that has a 22uF 0805 X5R 6.3V Chip Cap. It is placed on standard 0805 pads but is 1.25 mm high and although we are not getting the best fillet it appears sufficient. The trouble is we are getting a small number of returns

Howdy all. The question that I have is on wave solder pallets. I'm getting quite a bit of flux trapped on the pcb where it contacts the wave solder pallet. I have an appropriate profile for my assemblies, The flux that i use is Kester 920-CXF No Cl

I can understand the theory behind fewer tombstones with SAC. If people were having tombstone problems with SnPb eutectic solder, often switching to Sn62Pb36Ag2 would improve it, because with the addition of some silver, a small plastic zone in the
