![]() ![]() It is generally faster and easier to do it by hand under a scope, but only if you have experience. A re-work station (at least the ones I have access too) do not work that great with this type of connection on a PCB unless it's near brand new perfect with perfect pre-applied amounts of solder on the pads. If you do short the parallel leads, cleanup of the shorted pins is a bitch. Even with a fine tip quality solder iron, it is all too easy to short the connections with solder overflow and without a scope (unless you have kickass eyesight), it's hard to tell when they have shorted. Fixing traces is a bitch even for people who have done it a lot. If you have managed to rip the pads off the PCB, good luck. The biggest problem is that the pads/legs are "very" close together and parallel each other so when solder starts to flow, it tends to flow too much and short the parallel pads/pins in a cramped place that is hard to clean up (cramped because of the close proximity of the pins to too-easily melted plastic on the connector). I only use brand new ones for replacements and it's still a pain. Just getting a good SATA connector to use to replace/fix the broken one is a pain as trying to remove a SATA connector from another part without melting, bending pins, etc is a pain in the ass. Depending how it broke, there is probably a lot of clean up you have to perform, even before you get a chance to try and attach a different SATA connector. And no it's not easy to fix without the proper gear, and even with proper gear, experience comes into play. With SATA connectors, generally when it breaks it breaks the tongue (the male part that sticks into the female slot), the connector legs (the metal pins that connect to the PCB), or the pads on the PCS (the flat part the metal legs of the connector solder to). I will provide more details on these parts in another post.Īs always, if you need more information on the Cactus products to assist with a design, Talk to a Cactus Expert.It depends on exactly how you broke it. Other SATA Modules To round out the Cactus SATA interface offering, we have CFast products which are defined by the CompactFlash Association and possibly a future M.2 (NGFF) form factor.Ĭactus offers both an Industrial Grade CFast and MLC CFast card to meet different OEM market requirements. PIN #ĭEVICE ACTIVITY/DISABLE STAGGERED SPIN UP There are a total of 52-pins, with 26-pins on each side of the circuit board.īelow is a detailed signal breakdown as used on the Cactus Industrial Grade mSATA SSD. The mSATA (MO-300) uses a slightly different connector than the 2.5” and Slim SATA. The detailed signal breakdown as used on the Cactus Industrial Grade SATA SSD are shown in the table below. This is done to make sure the devices start up properly when hot swapping. As you can see by the image, some pads are longer so they will make contact sooner when the connector is inserted. That means that SATA tech is likely to run for well over a million hours before it needs to be replaced 7. The MTBF (mean time before failure) of SATA is 1.2 to 1.6 million hours. ![]() On the bright side, SAS hardware is more durable than SATA. The contact pads for these products is only found on one side of the connector. SAS hardware is more complicated, and that makes it more expensive. There are a total of 22-pins broken into 7-pins for Data and 15-pins for Power. The standard SATA connector found on 2.5” SATA SSD and Slim SATA (MO-297) are the same as shown above. A Brief History of the SATA Interface Revisions SATA VERSIONīACKWARD COMPATIBLE WITH SATA 1.5 GBITS/SECīACKWARD COMPATIBLE WITH SATA 3.0 GBITS/SECĢ.5" SATA SSD and Slim SATA (MO-297) Connector The ATA/ATAPI basic interface commands used for the earlier PATA interface are supported by SATA to make the command set backward compatible. Higher SATA speeds were arrived at by a much increased data rate on serial paired lines for transmit and receive. The SATA interface was designed to be a much faster interface than PATA. The Serial ATA (SATA) interface was created in 2003 by the Serial ATA Working Group, which was later incorporated as a non-profit named the Serial ATA International Organization (SATA-IO). SATA stands for Serial ATA and is the follow-on interface to the PATA (Parallel ATA) interface originally designed in 1986. SATA is a computer bus specifically for connecting mass storage devices to host systems. ![]()
