Pete C We do bake our tray parts. I am familiar with the ipc specs. The problem is for example: a level 4 component can only be out a total of 72 hrs before rebake is required. If this is a tube or reel part, the 125c bake temp that is recommended wi

The front plate of the S15 head gives you access to the signal amplifier boards. You'll find 4 potentiometers adjusting the voltage and the symmetry of track A and B. A digital scope turned to X+Y provides an image of a circle, which is been adjusted

1)Solder paste selection 2)Reflow profile.Focus on soaking and TAL. 3)Moisture control for BGA. 4)Maybe the BGA solder ball already with void. 5)PCB design.Any via on bga land? 6)Solder masking type. 7)Solder paste volume apply on land. 8)IPC class 3

IF you open up your TV, cd player or color printer you will see RA / RMA flux ON EVERYTHING! The waxy binder protects the halogenated compounds from becoming active with atmospheric moisture. Self healing is a good way to look at it. However, OA is

Hi Eric, Every mounter have a standard count and "release" off the component. The sample and cost saving way is to use the paper (e.g: 4mil,5mil...thick) to measure. Just place on the PCB with supoort base below and release the nozzle step by

Have you taken a look at our SolderStar range of profilers. We offer 4,6 and 12 channel versions. Our 12 channel system can also be connected to our Wave Shuttle product for wave solder machine analysis. Our datalogger are the smallest reflow profile

We are looking at several reflow ovens with intent to acquire one for both air and nitrogen reflow capability (i.e. have the capability to reflow in either air or nitrogen environment). Would be interested to know what I should look for in comparing
