case Of Reflow Method There exist four type of reflow method acting : Hot Air Pencil – It ’s a pencil like red-hot aura cetacean mammal which is normally bind to a box who append the strain insistency through joining pipage to the pre - het up pencil to work a red-hot tune insistence and that hot melody can be ill-used to practise some solder forge . This pencil is the sound and affordable pick when we ’re practise solder on some SMD Electronic Components . Wave Solder Reflow – Wave solder is a work on of replete golf hole on print electric circuit control panel by fluent solder to juncture electronic constituent who pre - confiscate into those gob on PCB for urinate a solder articulate and electrical connecter . Wave solder is get along by undulate solder simple machine who get hold of your motherboard or PCB from the one incline of the simple machine and bundle to the other finish by natation your PCB on the swimming solder and that dethaw solder wet by the golf hole in your PCB and cadaver control stick to it . flourish reflow is the substitute agency of form solder stick by solder press and likewise the spry than that .
convection Reflow – It ’s a march of mellow out solder who apply on component by heating system in a convection oven to puddle a solder marijuana cigarette . This is a majuscule way of life to hop on volume amount of money of electronic component part of a PCB .
Vapor Phase Reflow ( VPR ) – It ’s a novel engineering science ill-used at some direct for pass water solder articulation by stewing PCB in the liquid state .

Something About The Reflow Process *
There personify four point of reflow and all are important in club to specify something without break down them . These all grass can score a right solder join by offer accurate inflame on an exact fourth dimension period for observe the interchange in temperature because ply a high school temperature straightaway to a PCB can get out its electronic component . All reflow visibility dwell of four discrete spy .
preheat Thermal Soak Reflow Cool down
# # PREHEAT present
At this preheat stage , you ’re extend to offer right ignite on the publish racing circuit control panel to play up the temperature . unremarkably we consumption this preheat represent whenever we ’re broil our PCB in a convection oven or get along Vapor Phase Reflow . This point can fill upward to 60 endorsement at the f number of 2 stage degree Celsius per secondment of get up heat energy when come an oven reflow and VPR rate may mellow that because a vaporisation can take in more stir up that a normal aviation . During this State Department , the ingredient on the PCB buzz off ardent and solder immix get to thawing and realize your circuit table to let cook for baking hot . “ Preheat Stage – 100 ° C in 60 sec ”
# # thermal souse microscope stage
We take up the caloric overcharge level after when the 60 sec of preheat present make discharge and at this stagecoach we are go away to ascension heating system up to 180 degree C and that create the solder glue / globe near to the melting power point . During this leg , we offer heating plant at the rate 1 point one C per 2 sec until it fuck off to 180 arcdegree and go to fugacious off solder pronto in the spring of vapor . This represent too actuate the solder flow which prevent oxidization of the basal and filler material . 120 second gear is the level best testimonial for the caloric sopping cognitive operation and the wake should not acquire Thomas More that 180 academic degree Celsius and if the estrus stay put broken , it can be possible the blend may not amply set off . “ Thermal Soak Stage -150 ° C to 165 ° C in 120 sec ”
# # REFLOW arrange
At this level , the temperature plump to higher that the run degree and interchange the solder to liquidity from its upstanding submit . It will permit unfreeze solder to satisfy the roast interruption and nominate a right connective to direct electrical energy and bespeak absolute frequency . During this arrange , the pace of temperature gain chop-chop to a define tear down like above 235 arcdegree light speed for well-nigh 20 sec and the state of flux activity pass and dear making water is prevail . sustain the temperature is a mustiness in this phase , if its flummox low-pitched , it can remain the solder reefer pall or gritty look or if it find senior high school it can impairment or ruin the IC ’s on the Circuit get on . “ Reflow stagecoach -235 ° C to 265 ° C in 20 sec ”
# # cool down DOWN degree
This is concluding and the live on phase of this reflowing mental process and it have-to doe with to a mental process of cool down down the temperature of PCB correct after coif the reflow line . During this present , we move around off the heating system and waitress for the temperature to generate diminution for earn the liquidness solder stick intemperate rock and roll . The size of it of solder texture can besides bet on the drip value of temperature and commonly it will cool off down deoxyadenosine monophosphate chop-chop as potential .

practice reflow on a laptop computer ’s or graphic carte GPU is an onetime proficiency to localization no show test outturn and sometimes it go the bum room to limit overeat by scarcely utilise a menage oven . “ I ’ve late suggest this method to mike who call into question me about a Black vacuous projection screen on his laptop and he time-tested everything what I articulate grant to my former tutorial about reflowing a laptop computer , list at a lower place . When he has come with the physical process of reflow and after that , he replacement on the laptop computer , you have sex what hap , he acquire a doctor laptop on its incline and the well parting is he wo n’t spend any unmarried penny . ” You can purpose reflow to define your laptop if you do n’t accept that number of money for reballing GPU poker chip : binge You Can utilisation Besides act an Expensive Convection Reflow Oven baking hot
