Square-leaded pin headers will typically bridge at the trailing edge (last couple of leads), since during peel-back, the solder at the trailing edge has "nowhere to go". If you have control over designs, ask your designers if they can put solder thi

Keep in mind that device pitch, pad geometry, lead length and even alloy type will play a roll in your evaluation. I have an assembly that we run 10k pieces per month. One two-pin connector has a pitch of 1.27mm. Unfortunately, the pads are 0.007"

Made no changes to pip process for lead free. Everything stayed the same. just have to ensure that components can withstand the high reflow temp. incomplete hole fill is from aperture not being big enough. Many people forget that paste reduces in

We would be able to help you in any way that we can. There was an article in SMT magazine that explains a lot. Also, we have data on other processes that have successfully done this conversion. This has been a popular way of eliminating the conver

Good morning, The critical points for successful PIP technology are: 1. Gap between THT lead and PHT hole. It shouldn�t be greater that 0.2mm; 2. Lead shape. THT leads MUST be straight or you�ll get excessive voiding otherwise; 3. As Russ said, pas

Todd, It's been a while since I have looked at this but I believe the IP-1 does not have a relay board for the feeders. +24 Vdc is wired to a pin on the connector and the I/O board (NO 3 I think) switches the ground. If you don't have +24 Vdc at 1

Sorry Dave? There is a seperate table safely hidden away in the D version, but i dont know if it is something new. chapter 7 THT - 7.5.5 Supported holes - solder has a table specifically for PIP, table 7-7 Plated trough holes with component leads -

(Its a flex head) I have made a trial program to determine at what point it stops. This is how it goes: I load the program, push the start button it will zero and pick components with head 1. As soon as it finishes placing head 1 parts it halts wher

I believe you are describing a pin in paste process. Not sure where a stencil is involved. Depending on you machine/pump, you can do damage to it by running paste thru it. Paste is a metal and will wear out internal parts. Also, most pastes used
