I've used these a bit too. I have found that the legs can be difficult to s= queeze to release and remove. Especially for fat fingers. Plus, make sure i= n placement there is adequate space around the body to fit the fingers in! = In one PCB we had an electro near-ish to the plug making it virtually impos= sible to squeeze the legs to get it out. Since we had the pads as a "component" to allow placement of the footprint,= we also had to mark them as "DNF" so they didn't appear in the BOM. Our CM= wanted to procure them (i.e. the PCB side).=20 Stephen -----Original Message----- From: piclist-bounces@mit.edu [mailto:piclist-bounces@mit.edu] On Behalf Of= Harold Hallikainen Sent: Tuesday, 30 January 2018 3:27 PM To: Microcontroller discussion list - Public. Subject: Re: [PIC] Tag-Connect I've been using these for several years. The "legged" versions have a fairl= y large footprint, but are good for debug. The legless versions need to be = held in place, but work well for production programming. The clips to hold = the legless version in place are marginal and VERY easy to lose. I've thought about undersizing the holes for the alignment pins a bit so th= e board would hold the alignment pins securely, but I have not done that. M= ost of my stuff has holes for the legs. A couple products don't have room t= hough, so I lost a bunch of retaining clips while debugging.
