The two first level cuts at comparing placement machines are: * Placement rate * Range of component capabilities This boils-down approximately to machine price. Virtually, everyone's feeders are priced similarly. Go to "Circuits Assembly" magazine

Solder Balls and Humidity

Electronics Forum | Thu Aug 23 16:28:14 EDT 2007 | grics

I want to get a collective opinion from the forum... I was always under the impression that Humidity at SMT can be a disaster and can cause solder balls... But what about at the Wave/Selective solder? If every board or almost every board has solder

SPC and Wave

Electronics Forum | Fri Jul 15 12:41:56 EDT 2005 | russ

You are not wrong in monitoring the Product (your really not monitoring the process). This methodology is valuable if your process is unstable (SPC is used to stabilize process). There is value in "real time" inspection of a process's product as lon

N2 and Voiding??

Electronics Forum | Thu Oct 18 11:08:22 EDT 2012 | scottp

Since we follow IPC Class III, I've done experiments turning N2 on and off and measuring void level with both SnPb and SAC305 solder. In both cases there was a statistically significant, measurable increase in voids with N2, but it wasn't significan

Spacing and Yield

Electronics Forum | Tue Sep 18 11:34:36 EDT 2001 | jschake

The tightest spacing between neighboring 0201 components assembled was 8-mils. Please refer to the response for the query entitled �Minimizing Tombstoning Defects� posted by martys, as the response provided there is also relevant to address this que

AOI, Quality and SPC

Electronics Forum | Thu Mar 06 11:37:17 EST 2003 | msivigny

Hello Phil, sorry for the confusion, because of our level of defect control and tracking at each process step, we did not use AOI systems at the time. We had a manual inspection station after reflow, then ICT and Functional/Final test for each produc

pick and place vaccum

Electronics Forum | Mon Nov 10 13:27:07 EST 2008 | evtimov

Hi janz, you should be aware of everything. You are going to change subsystem on your machine. How much vacuum you need on the machine? Can you control the vacuum level with your system? Can you control the the system at all? Is it really much more

IP1 and SSOP28

Electronics Forum | Tue May 18 16:40:22 EDT 2010 | m79d

I am having some problems getting the IP1 to place a SSOP28 package,pitch 0.65mm lead width 0.3mm. I am selecting computer vision 012 (tried 011) and vision type 100. EL data was put in looking at the datasheet and also measuring the device. Have tri

IP1 and SSOP28

Electronics Forum | Tue May 18 21:43:02 EDT 2010 | ashley

Hello mickd, 1) The EL data & Vision_type is NOT necessary when using MCS30 for IP1 machine. note : your input of the above might have cause confusion during VP, hence the OS error. 2) I would suggest the following... 2a) lower the Lead_check_are

Manncorp Pick and Place

Electronics Forum | Mon Aug 04 12:28:42 EDT 2014 | dyoungquist

Mydata (recently changed name to Micronic) will be more expensive than Manncorp but from my experience using Mydata, they are well worth the money. Tech support (in the USA at least) is very good if you go through them to buy the machines. You can
