We have evaluated using WS-629 and our feelings are that the formula is not very stable. One evaluation showed great results; superior solder joint appearance and good printability. The paste would not roll on another evaluation nor would it release

| I am currently using Alpha WS629. I have a Malcom SPS-1 Solder paste mixer. I find that the mixer after running for the recommended mixing time | (10 to 18 Min) ball's the solder in the jar. | | 1) Is there any other Manufacture having the same

We are now using solder paste(OM325) and I have some problems on the folowing process: 1. We use the solder paste softer(Malcom SP-1) to warm-up for 20 mins, when it just take from refrigerator. Is there any problems for solderpaste performance? 2.

Chris: I'm unsure about the kits you seek. Solderability of: * Components: J-STD-002, Dip And Look Method. Malcom Instruments makes a very nice tester. * Boards: IPC TM-650 2.4.12A Solderability, Edge Dip Method Good luck Dave F

Hi dave, Thanks for the input. your valuable feedback always help. which method is better Spindle or T-bar. IPC TM 650 have are considered as standard methods. 1. T bar 2. Spindle. since we have never used it. we are bit confused. Which would be

| who can tell me how viscosity measurements are really effective in smt process control? what can I monitor? Is it depending from fine pitch size? | Thanks a lot. | g. d'andrea | People write books on SMT process control. What's your problem? I

We would like to start testing our lead free wave solder machines in house. Mostly looking for lead and copper content. Malcom makes a relatively inexpensive machine that does this (STA-1 http://www.malcomtech.com/products_sta1.html). Does anyone

I've used ECD's WaveRIDER and TIC's Wave Optimizer, and some people have sworn by Malcom's wave reader as well (if you look at all the past threads). We HAD an optimizer here in our shop, but somebody bwoke it. :-( As for evaluating these, see Chu

The variables to study: * Dwell Time * Contact Length * Conveyor Speed * Parallelism * Top-side Substrate Temperature Before wave * Solder Pot temperature All of these variables are inter-related (ie changing one variable will affect another)
