Useful app note about board thermal design management from Toshiba Semiconductors. Link here (PDF) Power Semiconductor SMD type in automotive and high-power electronic applications are becoming exposed to increasingly high temperature because of a reduction in system size, an increase in board assembly density, and an increase in system power consumption due to performance enhancement.

Using 0603 surface mount components for prototyping
Kenneth Finnegan shared a tip on using 0603 SMDs on the .1″ perf board: As a quick little tip, when I’m prototyping circuits on 0.1″ perf board, I like using 0603 surface mount components for all of my passives and LEDs, since they nicely fit between the pads. This way I don’t need to bother with any […]
DIY Moteino guide
Felix writes, “I posted a short illustrated guide for making your own Moteino from SMD components. It also includes details how to burn the bootloader and fuses. Check it out here. Thanks and credit goes to forum user LukaQ for his contribution of the images and test sketches in this guide! See the full post […]
Halogen floodlight SMT reflow
David Sanz Kirbis built his own reflow device with an halogen floodlight, that is available on Github: First test was to check the speed of the temperature rise inside a standard halogen floodlight. Reflow soldering temperature curves are quite demanding, and some adapted ovens can’t reach the degrees-per-second speed of the ramp-up stages of these curves. […]
SMD edge connectors
Facelesstech has written an article describing a technique he used for connecting two boards together. More details at Facelesstech’s blog. Check out the video after the break.
App note: Surface Mount Rework Considerations
Old app note from Weller on Surface mount rework. Link here(PDF!). We know you can relate to the challenges presented by newer and more complex surface mount component packages. As systems continue to evolve, rework tasks can be increasingly difficult even for the most skilled rework technicians. The process of safely and efficiently removing and […]
Powerful Arduino Proto Board
ariefadha shared his ZuC Proto Board (Z-micro Controller Proto Board) project in the forum: 3 month ago i develop proto board / perf board that can fit SMD and also PTH. this proto board also have 2 ISP holes and micro USB. But Arduino use non-standard pin spacing so i put the arduino spacing on this […]
LCD clock version 2 – part I
Kevin Rye posted an update on his LCD clock project: Now that I’ve spent some time working with SMD Atmegas, I decided to redo the PCB to make it all SMD. By moving the Atmega to the SMD version, I picked up some additional space on the PCB. That allowed me to add a 4th button […]
SMD soldering station for Weller soldering tips
Martin Kumm writes: This page provides documents about a cheap SMD solder station built as an Arduino shield (Arduino UNO). It supports active soldering tips from Weller (RT series) which contain the heating element as well as a sensor and provides a standard 3.5 mm jack. Together with the corresponding female connector you will get […]
Experience with the TM240A pick and place
Chuck of LinearLogiX writes: We bought the TM240A and found it works pretty good for our needs. A couple items I found was that using the SMD type tant caps on a reel, I had to actually Grind the side to open width so the plastic holder would fit. As you can see in the pictures it would […]
Simple SMD LED tester
Peter over at Electronics-Lab posted an article describing how he designed and built his simple SMD LED tester: This project is a simple LED tester and LED polarity checker. It can be used to check 1206, 0805, 0603 and 5mm LEDs. All parts are readily available and they are very cheap. Usage is very simple. Just press the […]
SMD soldering on hot sand
This video by Oliver Krohn demonstrates how to solder SMD parts on hot sand: Soldering on hot sand using a bunsen burner or frying pan / oven. In this case I bought a SOIC breakout board and had to solder the chip onto it. Via Hacked Gadgets.
Surface-mount 555 PWM circuit
Nick Leijenhorst writes: I wanted to dim my room LED lighting with a potentiometer, and decided on creating a solution from scratch to make it more fun and educative. I decided to go with the fairly well-known 555 PWM circuit. To decrease size and for learning purposes I decided on using surface-mount components for the […]
Kevin’s LED tester
Kevin Rye designed a simple LED tester: I decide to put together a small LED Tester board. It’ll be powered by a small coin cell battery. I can pick up an LED with a pair of tweezers and just simply tap it to the solder pads. If it lights up, I know I’m holding it […]
PCB a Week 18: SMD Practice Skull
Mats continues his challenge of designing one PCB every week. In week 18 he came up with SMD Practice Skull: I while ago I chatted with (Re:load) Nick Johnson about making some simple pcbs for learning how to solder smd parts. This is one of the boards that I came up with. All parts are […]
Blingtag project
Mats posted the new version of his old project, the Blingtag: I wanted to redo an old project and convert it from SMD to “surface mounted thru hole parts” with the extra twist of having the parts *inside* the PCB.
Will the SMD resistors marking become a history?
Will the SMD resistors marking become a history? Company YAGEO announced its intention to remove marking of RC/AC 0603,0805,1206 SMD chip resistors from July, 1-st, 2013. Everything implies, that the situation with marking of chip resistors (0603/0805/1206) will soon be similar to chip capacitors – i.e. no marking on the top of the component. The […]
Tips & tricks to sort and rework surface mount devices (SMD)
Tips & tricks to sort and rework surface mount devices (SMD): I’m a member of the Superstition Amateur Radio Club (SARC) and each month we have a presentation on a ham radio related subject. I volunteered to record and upload the club’s monthly presentations. There were two presentations at the March 2013 club meeting: Tips […]
Mini SMD version of the solderiron driver
My mini SMD version. Size=LCD : ) hakko 907 works great +- 0.5C , but weller pes 51 with +- 10 C. dtmf shared his mini SMD version of the solderiron driver in the project log forum.
Tiny RGB stick string lighting
Pfriedel posted his RGB stick blinking lights in the project log forum: So to keep my iron hot and to give me something to keep practicing working with SMD devices, I’m about to order a run of about 30 tiny little 14x50mm stick blinkenlights. I figure as I finish them they’ll end up hanging over […]
