Rispondi a "How to Replace USB-C connector?"Order new port. - Watch video on how to get into phone without breaking stuff. (May need a Wagner heat gun from Home Depot - You should get a kit of nylon micro pry tools, spudgers with new port) - Have low-melting temperature solder (or Rose's metal) as well as fine rosin core 70%/30% lead/tin solder, good flux (or make your own with colophony and 99% isopropyl), flux remover spray and 99% alcohol and tiny brush and cotton swabs. Have good micro soldering iron and tip. Have good hot air rework station and PLENTY of experience and familiarity using it - must be at least 580Watt 100% duty cycle rating. Must understand pre-heat, interpass heat and post-heat requirements with hot air rework station to allow soldering iron tip to flow solder properly. Appreciate that connector plastics melt at just over 220 degrees C. You will be removing old connector with low melting temp solder and hot air workstation. Heavily flux old connector, apply low-melt solder to all pins and anchors of old port with medium sized...
Rispondi a "Has anyone replaced soldered ram in rmbp"RAM chips on a Retina are difficult to source and not an economically viable undertaking - not even including labor cost / risk. Micron has a look-up tool online where you find mfgr part number by entering the bottom code on the FBGA.

Trial and error / common sense (LOOK!, is there board flex? lose solder balls floating around?) / luck. The required tools needed are (at minimum) Quick 861DW hot air rework station (because of the 1000W power rating). Micron's data sheet or someone else's spec on soldering temps curve (you can manually control temp curve against timer with). You need skill and practice and nerve. You need an underheater. Trial and error. Belief in yourself. Make your own flux out of Colophony /99% alcohol to the consistency you want; runny. I would / could do it if it...
